Next trim the ends of the 6 seams back to hide under the parachute.
Add reinforcement rings at the corners and string.

If the intersection in the middle doesn't quite line up or got messed up just cut a spill hole.

The yellow parachute I did by making the two halves (3 pieces each) and then joined the halves together. That may work a little easier than trying to seal in the last piece.

So this is barely a proof of concept. All suggestions and info are wanted and welcomed.
Thanks for reading and save the cool and colorful shopping bags this holiday season.
