The specific ones are the RABOM ones that I saw. Do you want the tension bar to be removable so it is easier to glue the bow, or am I thinking about another part? Also, how about the Grosgrain ribbon quality? I know that the 100% acetate is best, but very pricey, like $0.60 per yd for 3/8" solid! I have seen some really poor quality grosgrain from AC Moore, but I don't know what makes it so bad verses good quality and I don't want to order a bunch from a website that is not good quality, ykwim?
