To make half square triangles that will finish 2″ from 5″ squares this is what you need:
Two 5″ squares – one dark and one light.
2. Draw lines to connect the marks.
3. Place the light square right-sides together with a dark 5″ square. Stitch along side the drawn line but not right on it – about one thread width to the outside of the drawn diagonal lines (towards the corners). This is to allow for the thickness of the thread in the seam allowance and the pressing of the fabric over the seam.
4. Cut the unit in half lengthwise and crosswise at the 2 1/2″ marks. Each resulting unit will measure 2 1/2″ square.
5. Test the alignment of the triangle edges with the square. If desired, you may stitch a second seam 1/2″ away from the first seam to sew your waste triangles together before cutting them away.
6. Done! Four half square triangle units that should measure 2 1/2″ unfinished and will finish at 2″.
And of course you are able to make these from 2 1/2″ strips using a ruler to cut the triangles- but the challenge I give myself is, “If I only have 5″ squares what can I do with them?”
Stay tuned for an upcoming blog post with a quilt block that will use these little guys!
