My mom has been saving Birdseed bags and Dogfood bags for me to make these...they're definitely a conversation-starter! I use scrap fabrics to line them, usually a thicker dark fabric if I've got it, or felt might even work. The red "Old Roy" bag has black corduroy on the inside
and the handles are made from clear aquarium tubing. I made myself a blue one with a cell-phone pocket on the side, and it's now my favorite bag!
The pattern was traced from a "market bag" that I bought years ago when I was in Mexico...I really like the rounded-bottom shape. It's only three pieces sewn together (the bottom and sides are one long rectangle), plus the lining. I posted a blog a week or so ago which has a few more photos of different variation, plus additional info on how I attach the handles---http://www.twistedtextiles.com/2008/06/20/now-with-new-shapes-and-colors/
I'm a bit addicted to making these ...I've got two others started, and I'm trying to find some cat food bags to try next
Of course, I sometimes really have to scrub the bags to get the oils off them...most pet foods have some terrible stuff in it

and I finished these this morning...
