The material I used is not of the canvas type, it is very flowing & a fairly loose woven fabrick. This gives all the folds when the cape is draped over the shoulder, yet bunches up very nicely when thrown over the back-the position it is usually in during ESB screen time. the stuff I got was already colored grey/brown, but you could probably get white easier & dye the whole thing. I plan on experimenting with this as well. If I could find this fabric in any large size, Id probably buy a whole bolt of it & make a bunch of capes. As luck would have it, I have never been able to find a good cape fabric in pieces larger than 2 yards that is the correct color, (& I've been looking for a long time.) the spraypaint I used for the stripe is found at tractor supply. look in the tractor/implement section. The can actually says tractor & implement on the front of it, & is made by BPS. The color is Kubuta orange, & the # is 5339-24. Hope that gives ya some direction, & thanx for the comments,
