The computer is back with a new keyboard, Jack is back with new arteries around his heart - well, not really new because they were taken from his left leg - and I'm back. Thanks for all the kind comments on my previous post, I appreciate your support!
Maria Wallin's Biabag tutorial to help me, but I made the bag bigger and simpler. I used two fabrics instead of three, no interfacing and left off the side pockets and the pocket with a flap. I'm pleased with how it turned out, but I'm not sure that I'm well suited to a bag with a lot of pockets - you have to remember which pocket a thing is in, and put it back in the same pocket when you're done with it!
