Here is the simple bag I just finished. I has no separate lining, just fuse two pieces of fabric together to make a heavier fabric. There are pockets on the outside, and the inside. I finished the edges with a wavy stitch so there would be little raveling.
The way the zipper is put in makes it open well.
Here you can see the inside pocets. No zippers, no velcro, just simple pockets to put stuff in. I think I'll make some for gifts!
