I had a couple of bags that I wanted to use the space a little more efficiently. I liked the idea of the velcro lined devider in MPB a lot. It allows me customize the use, and to have more things accessable in a deep bag, instead of just having things buried under each other at the bottom of the bag. One day as we were throwing out the lid to a large plastic storage tub I got the idea to cut it down to the size panel I needed for a given camera bag. I then went to Walmart, and got a box of adhesive backed velcro. It is heavy duty, has both sides, and comes about 5 feet long. I used the hook side to cover one side of the panel, and the loop side to cover the other side of the panel. Trimmed the excess, and dropped it in the bag. It makes for a very sturdy divider that allows me to customize each bag I have. Now I can attach any velcro backed item anywhere in the bag, and it doesn't all get lost at the bottom. Most nylon holster are very easy to sew velcro onto, and nylon webbing is useful formaking many types of holders. Attach velcro to the back, and place it anywhere in the bag you like.
