I bought the bags to see if it was simpler to buy them already made, or to make them myself. They are great little stuff sacks, but I did (with both machine- and hand-stitching) properly finish all of the seams, and re-do some of the seams completely. Now, if I end up using the bags a lot, I won't have to worry about the fabric at the seams coming unravelled. If I were making a bag from scratch, I'd have a greater seam allowance, and finish the seams properly as well.I bought the bags to see if it would be simpler to buy them already made, or to make them myself. Guess what I concluded? :-)If you don't mind about the seams, it's a very good deal.
