The camera case I've been using for a travel camera weighed a hefty 2.4 oz. So I made this lightweight camera case of fleece. I was concerned about a Ti tent stake or other hard object poking either the lens or the screen, if I toss it into my pack. So the area over the lens, and over the screen, is covered by a pocket, into which is inserted a layer of milk-carton plastic. Then the pocket is stitched closed with a zigzag stitch. So the tender areas of the camera get a "plastic sandwich"--two layers of fabric and one of plastic, for lightweight but decent protection. The case weighs 0.4 oz. Since I had to create a fairly accurate pattern, and refine it, I want to share the pattern. Sharing it makes me feel better about all the time it took to make it.
You'll need to cut two identical pieces of fabric, front and back. And two bits of plastic from a milk carton. The numbers give a rough guide regarding the order in which I'd recommend you tackle the project.
1) Cut the pocket flap(s), place the plastic beneath the pocket flap (making certain the fabric of the pocket is slightly larger than the plastic it encapsulates), pin it in place, and zigzag stitch the pocket shut. The plastic is now trapped inside two layers of fabric.
2) Cut on the solid lines. Fold, then tack these tabs in place.
3) I should not have numbered this 3, ignore.
4) Fold over and tack these tabs.
5) Fold up the drawstring pocket and sew shut (this includes folding under, along line 3).
6) sew up the bag on three sides.
If the camera fits too loose, stitch another line inside the previous to tighten the bag. If too tight, take out a line of stitching and sew another further away. Once it fits nicely, bartack the upper corners of the bag, and trim the excess fabric along the hem. Thread the cord, and you're done.
