Square-in-a-Square Quilt Block Tutorial

I love the Square-in-a-Square block for its simplicity, but it’s also terrific for learning to handle bias edges, and practicing great points. It’s also one of my favorites for using novelty or feature fabrics in the centers.  

The instructions below will make a 9″ finished (9.5″ unfinished) block. Start with the following:

Cut the 4″ solid squares in half diagonally.

Using a scant 1/4″ seam allowance, sew two triangles to opposite sides of the 5″ charm square. Remember that the diagonal side of the triangle is a bias edge. Sew with the triangle on the bottom (close to the feed dogs) to reduce stretching. You should have a little “ear” of fabric extending from both ends.

Press the triangles away from the center, and then repeat for the other two sides.

Press the triangles away from the center, and trim the “ears” from each side.

Cut the print 5 3/8″ squares diagonally.

Again sewing with the triangles close to the feed dogs, and the “ears” extending past the ends of the solid square, sew to opposite sides of the block. Carefully sew through (or just outside) the intersection of stitching lines. This will make perfect points for the center square.

Press the first two triangles away from the center, and then repeat for the last two sides.

Press the last two triangles away from the center, and admire your finished block!

Here’s a simple, random layout. 30 blocks plus 2″ and 4″ borders for a 58″x67″ quilt. Quick and easy, or with a bit more planning secondary stars and other designs will appear. Give it a try!
