These instructions make a 12 inch (finished, 12 1/2" including seams) Gretchen block. The Gretchen block is traditionally made up of only 2 colours. The following uses a series of light and darks with red and white prints for the pinwheel of each block.
- 4 x 4 7/8” squares light/medium
- 4 x 4 7/8” squares medium/dark
- 4 x 2 7/8” squares white
- 4 x 2 7/8” squares red
Pair light and and dark fabrics and sew into half square triangles. Separate finished squares into two matching sets.
Cut red and white squares diagonally. Pair white triangles with dark prints on one set of sewn squares. Sew triangles to dark fabric as shown. Pair red triangles with light prints on remaining set of sewn squares and sew. Press small triangles outwards. (if you are feeling thrifty, keep the offcut triangles for making something like this)
Place ruler over pieces from step 2, lining ruler edge with edge of red or white triangles and cut as shown. Sew units with red triangles to units with white triangles.
Combine pairs of subblocks. Ensure that the top red triangle is to the left of centre and white to the right, as shown. Sew and press 2 pairs.
Combine pairs to create finished block.
