I just got a shiny, new dslr camera and I was determined to lose that little lens cap. I left it everywhere. I was ready to buy a back-up, but decided to design a holder for it instead.
This pocket slides onto the camera strap. It closes with Velcro for one-handed opening. The flap keeps the cap from falling out.
This would make a great gift for a photographer! The full tutorial is on my website, or you can buy one in my CraftyStaci Etsy store.
