Assemble the Attic Windows Quilt BlocksIf necessary, use a straight pin to find seam intersections when you're sewing.
- Match the angled edge of a bottom sill with the angled edge of a short side sill, right sides together. Sew along the angled edge, beginning at the matched outer tips and ending the seam at the marked intersection. Backstitch a few stitches and remove from the machine. Press the seam open.
- Measure 1/4" inward on two sides of a small window square to find the seam intersection. Be sure to mark the corner that will fit into the angled edge of the sills.
- Place the square right along the partially sewn bottom sill, right sides together and aligning straight edges. The mark on the square should match the mark on the sill--the place where you stopped sewing.
- Start sewing from the matched straight edges, moving toward the angle of the sills. End the seam at the mark. Leave the unit in the machine, needle down.
- Pivot the unit and align the next side of the square with the other sill. Match the seam intersection again and begin sewing. Sew all the way to the end of the matched patches.
- Press seam allowances towards sills.
- Repeat to sew all squares and rectangles to their sill counterparts.
