How To Make A Pretty Nice lined Gun Case From An Old Army Dufflebag and Blanket!

Step 15 Stitch in Zipper.

Start by turning your bag inside out again. Lay your zipper carefully against the edges of the case. The main trick here is to be sure the lining, outer bag fabric and zipper edges all line up. You want those edges on the inside so that when you turn it back right side-out, there will be no stitches showing, and a neat little seam, just like you did with the rest of your bag.
