What are Half Square Triangles? It sounds complicated, doesn't it, but it is not.
It is a square of any size made up of two equal triangles. It is the basis for
many quilt block patterns.
- Cut a square the size needed for your block. It needs to be 7/8" larger
than your finished block size. If you need a 4" finished square, add 7/8" to that
measurement. This is includes the seam allowances, and includes compensation for
the triangles. Cut this square in half diagonally. Read
for further clarification of the amount to add to your finished square size.
- Sew two triangles right sides together with a ¼" seam allowance. Sew along
the long side of the triangle.
- You may press the seam to one side (pressing toward the darker fabric so
their isn't a shadow of the dark fabric showing through from the right side.)
I prefer to press these seams open. The block lies flatter when it is finished,
and it makes it easier for machine quilting later. The free motion quilting foot
glides over the seams more smoothly.
- There are some little points (wings) hanging out over the edge of the block
where the seam line is. Trimming these off lessens the bulk of fabric in your
quilt and makes it easier to hand and machine quilt.
- Press your block again but this time from the right side.
