Sometimes, it just nice to have triangle papers... Here is a lesson on how to draft Half Square Triangle (HST) Paper and sew HST units using your DIY Triangle Paper. I have tried SO many methods for making HSTs. And I have come to the realization that I just need to stick with using the paper triangle method. I can't seem to get sharp points any other way when they are smaller than 2" finished. First, let me say that I make a master copy of my DIY triangle papers. Draft once and make copies! That's my motto. Here are the tools I use: The apps QuiltPaper and QuiltSandwich, a black pen, a red pen and a ruler. That's it! Let's get started! As an overall observation as to where we are headed, what we are going to do is create squares using the cut size of the fabric, draw a diagonal line corner to corner. And then we are going to sew 1/4" away from the line. This tutorial is how to do that on graph paper for any size triangle you need. Just keep that in mind as you read through the steps. 1. Determine the finished size of the half square triangle needed. Let's say that I want to make a 9" Churn Dash block. My block has 3 pieces across. 9" divided by 3, means that my HST piece needs to finish at 3". Does this make sense? Or — 1 square equals 1". 2. Here is the magic secret. Triangle papers are drawn in cut sizes. Which means the seam allowance needs to be added to the finished size of my HST. How do I know how big to draw my cut size square? Well just look it up on the QuiltSandwich app!!! I just tap the scissors to look at the Cutting Diagram. To make a 3" finished HST, the Cutting Diagram tells me that I need to cut my squares 3 7/8". We are going to do exactly the same thing! But not to fear. Use the QuiltPaper app to create graph paper that has 8 lines to the inch. And this will be super easy! Here are screen shots from the QuiltPaper app to show you how I created my paper — QuiltPaper has a really cool feature where you can number the squares on the paper! This makes it so very very easy to count and keep track of where you are. 3. Making my HST paper. I want to make more than one unit at a time. So I am going to fit as many on my page as possible. Note that the QuiltPaper app will accommodate legal size paper AND A4 paperfor our overseas quilters. Also the margins are adjustable! I am using standard, 8 1/2 x 11, printer paper. First I draw a column, 3 7/8" wide. I am using my black pen for this. The black lines will end up being my cutting/trimming line. Then I divide it into 3 7/8" squares. I use black pen for this too. I know my lines are not very dark, but I am hoping you can see them OK. We are making HST, so now we need to draw a diagonal line. This is exactly the same as cutting out a square of fabric and drawing the diagonal line from corner to corner. This line is drawn in black too. Then I add my seam allowances. Just use the 1/4" mark on your ruler to draw the red line. Put the 1/4" mark on the diagonal line, and then draw the red line. I use my red pen to draw the seam allowances. Now that I think about it, you really don't need to draw the red lines. Sewing 1/4" away from the black line is that same as drawing a line on your fabric square and cutting it on the diagonal. But I am going to draw the red lines, just so you can get an idea as to how this works. And because purchased triangle papers tend to have the sewing lines (red) marked as well as the cutting lines (black) . And true confessions; I like to sew on the red line, I am just more accurate that way. 4. Make a copy. Remember, you are making a master Triangle Paper. 6. Lay your fabric strips right sides together. You can either pin them to the strip, or use a little dab of fabric glue. Once you get started sewing you won't need the pin anymore. Its just to hold everything together and straight to get started. One mistake I made in creating this tutorial is I didn't cut my strips long enough for me to make sure that I was placing them in the right place. The paper goes on top of the strips, because thats where the stitching lines are. So I cut off the excess top and bottom paper margins so you could see where I placed the fabric. 8. Wasn't that slick? No bias edges. No triangle tips getting eaten by the feed dogs. 9. Now just cut on the black lines. There you have it — perfectly sized HST that assembled measures 3 1/2" and will finish as 3". Remove the paper. I fold it back to make a crease. This makes it easier to tear. The key to easy tearing is the shorter stitch length. I know that it would be unusual to use a triangle paper for a triangle this size. But I wanted to use big pieces so that it would be easier for you all to see what I did. So as my gift to you, I am making available a sheet of 2" assembled HST, for you to download and try out. These HST will finish at 1 1/2". There are 2 PDFs. My "master" PDF and a PDF that shows what they look like after the triangle strips for piecing have been created. Consider using this page for copying too! Here's to joyful piecing!
