Step 2
Lay out the colored granny squares to decide the order. Once decided, turn squares to the wrong side. Using an embroidery needle threaded with yarn, whip stitch squares together, working first in vertical rows and then horizontal.
Step 3
Cut fabric to size of pillow form, plus a 1/2" seam allowance on each side for a snug-fitting pillow. Pin edges 1/2" down, and then pin pieced granny square front to it, both sides wrong side out. Sew together the pillow front and back with a sewing machine. Leave one side unstitched to insert pillow form.
