Bumping this thread - My wife is helping me with the sewing, ill post some pics asap but i got some materials today -
Trexx Black Vinyl (whether resistant)
Grey Flannel (for the inner lining)
Oval Elastic Cord & Plastic Cord Stopper Deals (for the cinch system around lens)
Black Velcro for the outer most sections where it opens up.
Currently fits good on my Gripped T2i with both my 70-300 & 18-55 lenses. Pretty cool project and this is the "prototype" If it turns out I might make a few for people I know. Ill post pics but I wanted something nicer, more usable than a plastic bag and I don't have 70.00 to spend on a Kata Cover
