1. Start with a purchased square or rectangular knife-edge
pillow insert—that’s the kind that tapers at the edges. Select a
pillow insert—we used a 12-in. x 12-in. size. The amount of
fabric you need will depend on your pillow size (we used less
than a yard), but the kind of fabric you choose is limited only
by your imagination!   2. Press fabric and lay it wrong side up
on a flat surface. Measure two pieces of fabric (see above for
pillow assembly diagram): A1 (add 1-in. to width and length of
your pillow insert); A2 (add 1-in. to width of your pillow
insert and 6-1/2-in. to the length). So for our 12 in. square
pillow, A1 is 13-in. square; A2 is 13-in. x 18-1/2-in. Cut
pieces A1 and A2.   3. Cut fabric piece A2 (refer to photo
above) into two 9-1/4-in. x 13-in. pieces. With wrong sides up,
fold a 1-1/2-in. hem along the cut edge of each piece to make
two 7-3/4-in. x 13 in. pieces, B1. Press hems in place. Fold
under 1/4-in. along the cut edge on each hem, B2; press. Sew
along edges of both folded hems as sh
