How to Sew Half Square Triangles
-
Lay your two pieces of fabric on top of each other right sides together.
-
Using your ruler, makr a line from on corner to the next. Really focus on reall making that mark corner to corner.
Tip: For extra measure, you can place one pin on each side through your fabrics to help hold them together. Be sure to palce the pins far away from your line. -
Sew a scant quarter of an inch on either side of the line.
-
Sew on either side of the line you made a scant quareter of an inch. Pull your fabric out when you reach the end, rotate it, and repeat.
Pro Tip: take a piece of washi tape, and using a tape measure, measure exactly where a quarter of an inch is on your sewing machine. You can usi this as a guide as you run your fabric along the sewing machine. -
You can remove your pins now that you have finished sewing. You are going to want to use your ruler and your rotary cutter to cut down the line that you previously drew.
-
Set your seams by giving them a quick run over with your iron. You now want to press your seams to one side.
-
Line up your fabric and ruler so that they are both at a 45 degree mark. Then, using your rotary cutter trip the edges that are sticking out from your ruler.
-
Repeat step 7 with the other side of your square, and your other square.
-
Now you have a perfectly pointed half square triangle!
