My friend said she couldn't find what she wanted for her cushions, so she asked me to make her two. We went to Hancock's Fabrics and found something she wanted, and the best part? they were on SALE!!!!
Fabric and trim
First, I hemmed all the sides so that the side lay flat
Now sewing the trim onto the hemmed sides
Onto the zipper
First layer: hemmed side, Second layer: trim, Third layer: zipper
then sewing the rest of the sides together with the trim
Very carefully sewing the corners
