Yep, you can use organza! No, I don't get any crumples or static. When I first started them I was buying off the bolt and rolling/folding the tulle up and then cutting 6" sections with scissors (a youtube tut did that), but the cuts were not straight at all! So then I tried with my rotary cutter & mat, and I still wasn't liking it. It also took FOREVER to do. The paper cutter really made it a lot faster, cleaner & STRAIGHT LINES. lol It's more fun for me since I could cut it so fast.
Tying takes about 30 minutes, but I don't do it all at once. I have a 6 1/2 month old who is a huge mama's boy!
GL! When you give it a try I'd love to see pics!
