I first saw this method from the book "It's A Wrap" (http://www.amazon.com/Its-Wrap-Sewing-Fabric-Baskets/dp/156477662X). So addicting.
I took the bowl/bag idea a step further to create a huge beach bag (probably a little too big, but I just couldn't stop). I was able to bring it on the plane as a carry on and put it under the seat in front of me.
Turned out a little more 'watermelony' looking that I had hoped, but it's summery!!!
I wish I had pictures as i was doing it, when I got to the end of sewing it, my head was inside the bag just to hold it up....actually pretty challenging.
a little misshapen from storage...
