Buy once, make all the HST's you'll ever need. Sew on the dash lines, cut on the solid lines of the X and then cut the final lines indicated by the scissors and you will have up to 8 half square triangles!
With our Easy Half Square Triangle Remarkable Tool you can make unlimited amounts of half square triangles! It fits perfectly over a 10”x10” layer cake precut square (or cut your own) but you can use it for any size block smaller than that. The easiest way to use this stencil is to match it to a center point on your cutting mat, with some painter’s tape, tape the stencil to the cutting mat on the left or right side (depending if your left or right handed). Then simply lift the stencil, place two squares with right sides together matching their center to the center mark on the cutting mat and pounce the markings to the top fabric. Sew on the dash lines, cut on the solid lines of the X and then cut the final lines indicated by the scissors and you will have 8 half square triangles!
