i dyed pretty thick gauze with kool aide the purple kool aide turns out a very pretty like pinky purple color. I just didnt completely completely wash it out. I wash it out ut not all the way. We've had them hanging for almsot a year or so and theys till look the same. I also have a few just white hanging that look nice.
I hung them with little nails or thumb tacks hammered in, But we have a crown molding type thing around the whole house so its not leaving noticeable holes. Some i did hooks and then tyed the material to the hooks. I wasn't too worried about ruining the material at the time. It doesn't look perfect, a little umm unprofessional i'll say but it's nice and they hang so nice and flowy when they are actually hung as opposed to on a rod. They didn't frey too much where the tiny holes are as far as I can tell. I also did this over the walls in a corner and put down dd's futon style crib mattress there. It's a great cozy area. The rest are over windows and sliding glass doors.
The material is expensive but at joanne's right now they have all kinds of 40% and 50% off coupons on regular price items, so each time i get a coupong i go and buy more gauze. It's about 5$ a yard but 50% off it's not too bad and I really like the gauze they have, they also have it in already dyed colors.
