Half Square Triangles: Part 2

I decided that I should have a rating system for each method of Half Square Triangles….because I’m cool like that. :-) There are advantages and disadvantages to each, but that way you’ll know how I feel about it.

To catch up – visit Part 1: The Traditional Method

Half-Square-Triangles

Today I’ll show you how to make 4 half square triangles from one square. I don’t know if there is technically a name for this…so I’m going to call it

The Square Stitch Method

 

 

I’ve given this 1 out of 5 stars. I do not like this method. There are two primary reasons.

  1. It leaves you with bias edges. This results in more distortion in piecing and also while pressing (because many of us iron rather than simply press).
  2. The math is not simple. If you want to get technical it requires the Pythagorean Theorem and you must know whether to take your seam allowances into account before or after using the Pythagorean Theorem.

The sewing is EASY!

PLEASE starch these bad boys! It will help with the bias distortion problem by stabilizing the bias.

Square Half Square Triangles

You’re going to put your two squares right sides together and simply sew around the entire outside edge of your squares with a quarter inch seam allowance!

Now you’ll make two diagonal cuts, and you’re almost done!

Rotate your mat, or flip your ruler and cut the second diagonal line.

And now you have 4 half square triangles!

Four Half Square Triangles

Iron the seam to the dark size and trim to size, just like with the Traditional Method.

The math I’ve seen with this method is really poor math (it’s more like a guesstimate) and no one tells you if that results in the the finished size, or unfinished size. In fact, I haven’t personally seen anyone give an equation starting from the finished size that you actually need.  And if you’re going to use it to replace HSTs in a pattern, you need to start there.  If you’re winging it and making up your own pattern, then you can skip the math all together.

So I a squared plus b squared equals c squared. I figured out seam allowances. I took square roots of numbers. And I tested this on several sized squares to see if my math worked. And all for you. That’s how much I love you. ;-) You will get odd numbers, round up. You can always trim down to size later. In fact, I added an extra 1/4 inch already so that if your cutting isn’t perfect, your ruler slips while cutting or your seam allowance is not perfect, you will be safe. (I prefer to trim a little off rather than be too small.)

Ready for some algebra? (Your middle school teacher would be proud.)

Square-Half-Square-Triangle-Math

 

Start with the finished size you need and add in your 1/2 inch seam allowance. Multiple this number by 1.414. And lastly add 0.75. This tells you the size squares you need in order to make 4 half square triangles! Whew! And now if our brains have not exploded, we can see how to actually make these.  Cut two squares to the correct size.

Be back next Monday with another HST method as part of the

Throwback Thursday: Halloween Shirts

Halloween Shirts

Is it too early for a Halloween Post? It’d be fun to do this again.  And there’d probably be less paint too! Back tomorrow with another Half Square Triangle post!

You may not realize that I’ve been blogging for years and years. The problem is I keep switching my blogs. I started out selling handmade items, then I switched to a fabric store. Then I redid my store and had a blog on the website and then I sold the website! Anyway, I thought it’d be fun to bring over some of that old content from blogs I still own here each Thursday for a “throw back” post. There is still some really good and useful stuff. :D And it’s fun!

My week has been….blah.  And I don’t want to complain and whine – so instead, I’ve been silent.  Anyway, now I’m happy it’s Friday!  Since tomorrow is Halloween (also Reformation Day, as a friend pointed out) I thought the kids needed something a little special to wear to school today.

Painted Eye Shirts

The idea for the shirt is from Regina of Creative Kismet.  You can find it on her Tutorial Page.

My children painted the eyes.  In my house, this is really really huge.  In fact, when my oldest son was in preschool and it was time to do an art project with paint – he refused.  His reason: “My mom doesn’t let me paint.”  And he is right.  I can barely handle crayons – so paint is something my children don’t see – like ever.  And yes, I have a huge amount of guilt over it because I feel I need to foster their creative sides.  So -anyway, I got out my paint and let them do the work.   And paint is not covering our entire house – only our downstairs bathroom sink and toilet.  *sigh*

Eye in the back - Shirt

You have to take note of the sword Taylor has down the back of his shirt.  And the juice box.  He’s such a funny boy. What more could a boy need?

Spider Dress

We tried to make Haley’s hair black this morning – it didn’t work so well.  But I still think she looks darn cute in her spooky spider dress.

All for now.  I really do have great plans for some blog posts….if I can just find the time!

See you tomorrow with more Half Square Triangle goodness! I’m excited by how many people are excited about this little series!

Half Square Triangles: Part 1

Half Square Triangles are one of those basics in quilt blocks.  Tons of patterns use them.  In fact, I just finished a top with hundreds of half square triangles. (I haven’t revealed much…but you’ve seen peeks over on instagram if you follow me there.)  Since I was making hundreds of HSTs (rather than type out half square triangle, I’ll use HST.  :D   ) I got to thinking about all the ways there are to make these units.

Half-Square-Triangles

So I thought I’d do a little study of HST’s here on the blog.

The Traditional Method

3-stars

 

I’ve given this 3 out of 5 stars.  It’s easy to understand and does not require an advanced degree in math.  It’s rather tedious to go back and trim each square (to square up or get rid of the dog ears.)

Yield: Two HSTs per two squares

This is great when you need to make a few HSTs.  It quickly becomes tedious when you have a large amount to make.

First of all, when you’re making HSTs, you need to know the finished size you need in the quilt.  (This is the final size after all the seams have been sewn!)  Add 7/8 inch to this size.*  That is the size square you will need to start.  You need two squares. (Shown here: white with Art Gallery‘s Nature Elements in Raspberry Tart.)

Half Square Triangles

So if you need 2 inch finished size – you’ll start with 2 7/8 inch squares. 3 inch finished = 3 7/8 inch starting squares. etc.

*Because I really like all my points to match up, I add 1 inch and trim my HST down to size.

Half Square Triangles - line

Next you’re going to put your squares right sides together and draw a line diagonally.

Half Square Triangles - sew

Sew 1/4 inch on both sides of the line, and use your ruler and rotary cutter to cut on that line.  Let your seam go over to the dark side. (Luke, I am your father.) In other words, press the seam toward the darker fabric.

Half Square Triangles - cut

You can totally use any ruler to trim up Half Square Triangles, but if you have a Joann’s coupon or are going to be making a tons of these bad boys , I’d recommend this ruler!  You simply line up your diagonal line, and trim to the size you desire.

June Tailor Half Square Triangle Ruler

And there you go!  That’s the traditional method for making Half Square Triangles.

Half Square Triangles - finished

But as I said, there are several other ways to make these.  (And they become super appealing when you need to make one hundred and fifty 2-inch HSTs!)  I will share those with you in the coming days.  :-)

Throwback Thursday: Kindergarten

Kindergarten and Kyle’s Blanket:

You may not realize that I’ve been blogging for years and years. The problem is I keep switching my blogs. I started out selling handmade items, then I switched to a fabric store. Then I redid my store and had a blog on the website and then I sold the website! Anyway, I thought it’d be fun to bring over some of that old content from blogs I still own here each Thursday for a “throw back” post. There is still some really good and useful stuff. :D   And it’s fun!

Originally posted 8-20-2007 about Kyle starting kindergarten and the blanket I made him. It’s fun to see the kids when they were little….but ALSO it’s amazing to look at the different level of sewing. What a difference 6 years makes!  A lesson in practice and longevity! (And sorry the pictures are so tiny. :-)   If I can find them on flickr, I’ll switch them out.)


Today is Kyle’s first day of kindergarten. Yesterday we went a bought a back pack for him. He picked out Spiderman! SUPER COOL :-) He’s hardly any bigger than it! He also got a Spiderman lunchpack. Haley is also starting preschool today. Her friend Sara is in her class and she’s very excited about that! She got a little backpack…I think a regular sized one would have swallowed her!




I also am putting a up pictures of Kyle’s new blanket. I made this special for him since he is starting school 5 days/week. (I make Haley clothes, but Kyle just seems to get left out! ) Anyway he got to pick out the fabric himself…I just put it together. Pretty good, huh? The only thing I thought was funny was that he picked out fleece for the back. Doesn’t the kid know we live in Arizona?!?!?!

Throw Back Thursday: Sewing Mom and Daughter Outfits

Sunday Dress: Sewing Mom and Daughter Outfits

You may not realize that I’ve been blogging for years and years.  The problem is I keep switching my blogs.  I started out selling handmade items, then I switched to a fabric store.  Then I redid my store and had a blog on the website and then I sold the website!  Anyway,  I thought it’d be fun to bring over some of that old content from blogs I still own here each Thursday for a “throw back” post.  There is still some really good and useful stuff.  :D

*****************************************

Haley is currently 5. (She is now 9!) She tells me “Mom, you’re as beautiful as a princess.” That’s pretty special, if you ask me!  This precious little girl looks up to me and I am so quick to focus on my flaws and inadequacies.  I’m really hard on myself.  And now I stop to think: What is that teaching my daughter about her self-worth? And what should I be doing differently? I actually have tears in my eyes thinking about it.  *sigh*

Sewing Mom and Daughter outfits

I hope I’m also passing on positive characteristics.  As she grows, I hope that by watching me, she’ll learn that through persistence and hard work you can overcome fears and obstacles.  And that it’s okay to ask for help.  (Oh, who am I kidding.  I haven’t come to terms with that myself.  Why is it so hard to ask for help?) And it’s okay to try new things.  I really want her to learn that.

Wow, this post has taken an unexpected sentimental turn.  Anywho… my original plan was to show you our matching outfits.

Mommy & Me outfits

 

Haley’s outfit is from Pink Fig’s Lilly pattern and my skirt was made using Rosie’s Whimsy tutorial. (Found here.) The fabric is more great fabric from Joel Dewberry‘s Modern Meadow line. And this isn’t the last we’ll see of it, either.

Oh, by the by, this isn’t the first matching set I’ve done for us.  I made myself the Schoolhouse Tunic (by Sew Liberated) to match her Kyoko (by ModKid) and I need to get the mini-kyoko made…then maybe we’ll do a quick photo shoot.  Gotta get in on this matchy goodness while she still thinks of me in the same realm as a princess.  Now…can someone tell me how I can become an actual princess?

*********************************************

I still am really hard on myself.  And my daughter still wears clothes that I make for her.  :-) Yay for handmade!  Happy Thursday!
