How to Piece Quarter Square Triangle
The first step to creating quarter square triangles is to make a set of half square triangles. Click here to find my tutorial on how to piece two half square triangles at a time.
The next step is to cut the half square triangles apart and carefully press the seam allowances open.
Yes, I think it's necessary to press your seam allowances open, especially when piecing a precise unit like quarter square triangles. I first finger press the seam allowance open because this seam is running on the bias, or the stretchiest angle on the fabric. Be gentle finger pressing this seam open then press with a hot, dry iron.
Once the half square triangles have been pressed flat, layer the unit right sides together with the corresponding square to make your quarter square triangles. Yes, the extra square will be bigger than the half square triangle shape.
Mark a diagonal line from corner to corner, just like how you made the half square triangles to start
Now we’re going to repeat the steps to making half square triangles - simply stitch 1/4 inch on both sides of the marked line. I use a patchwork foot to make stitching exactly ¼-inch inch from the center line easier and faster.
Next cut along the diagonal marked line and gently finger press the seam allowances open to create two quarter square triangle shapes.
The last step to making quarter square triangles is a bit tricky. Carefully line up your ruler to trim the unit down precisely using the diagonal pieced lines as a guide. Take your time trimming the unit carefully so it finishes exactly the right size for your leaf block.
