What You'll Need:
1 yard each of 2 coordinating fabrics.(If you only want it to be one sided, you only need the one fabric)
Thread and sewing machine
Cut your fabric pieces to be 33 inches by 45 inches. For mine, I kept the edges squared, but if you want rounded edges, you can use a plate to trace.
Lay the pieces of fabric pattern side together. Pin the edges together. Sew around 3 1/2 sides, leaving at least 8 inches un-sewed to flip the fabric right side out.
Flip the fabric right side out, and sew the last 8 inches. Add the top stitch.
With your fabric scraps, cut out 4 pieces that are about 10 inches long, and 3 inches wide. The length will depend on how you sew your velcro. I planned to make my straps longer so the velcro overlaps more. You want 2 pieces of each fabric.
Sew them pattern side together, leaving one end open to flip it right side out. Add the top stitch.
Sew your velcro on, making the soft velcro on one side, and the hook velcro on the other.
When you have your straps made, pin them on the canopy. I positioned mine to be exactly in the middle (lengthwise), and with about 5 inches between them (width wise).Place your pins about an inch apart, and sew across the straps where you pinned.
Make sure you try it on your car seat before sewing! Each car seat (and their handles) are made differently, and yours may fit a bit different than mine.
