I went into to our local fabric store that is HUGE and carries everything imaginable including a large array of rhinestones (loose, banded, netted, colors, many sizes, gold, silver, black settings, etc - I was in hog heaven!). I bought 3 3/4 yds of a double strand set in a silver colored metal (stainless, foil, etc?), decent size stones and highly reflective without being irridescent. Apparently they sell a lot to the local decorators because she told me I needed a triple band; it was more common on cakes. I liked the double.
Point is after doing the math (2*pi*r + 2*pi*r +...+...+...) it came to over $50 with tax for less than 4 yards. I did buy an extra 1/4 yard, just in case i needed it. Do most of you sell these to the cake buyer or do most rent these, with a deposit no doubt, to the customer? This particular purchase is for a dummy cake for a store front window.
