How to Make Eight Half Square Triangles at Once!
The Magic 8 method is certainly not original with me, but I thought it was worth sharing since I’ve been using it religiously on one of my newest designs (It’s called Breezy, and you’re going to love it! It will be releasing sometime in April.) Anyway, there are lots of ways to make Half Square Triangles, but this method is the fastest and most precise that I’ve found.
How To Make Half Square Triangles…Fast!
First, you’ll need to cut a square. I’ve got a handy chart here for you so that you know what size square to cut in order to get eight Half Square Triangles in the size you’re looking for.
So, if you want a finished 3″ square (2-1/2″ once it’s sewn, or finished), you’ll need to cut a 7″ square.
Then you’ll trace some lines on the back using a ruler or a tool called the Magic Wand by Deb Tucker.
If you’re not using the Magic Wand, you’ll first draw 2 lines from corner to corner on the back of your Background 7″ Square. Next, draw a line 1/4″ on either side of the lines you just drew. Now draw a line across each center point for a total of 8 lines (first image above).
Next, match your drawn-on square with another 7″ square, right sides together.
Sew on the offset diagonal lines (dotted lines in the second image above).
Cut on the unsewn lines (the solid lines) to create 8 half square triangles.
Press seams away from background fabric and trim dog ears. Each square should equal just a little bit more than 3.” You can trim it down to be exactly 3.”
Pretty fancy, eh!?
