Some may be shipped in the kits: * Tape strips are sold for costumes and wigs: * 3M's super strong 300LSE in letter sheets, ~$12 each: ** these are an excellent option. 3M sells [24x36" sheets]( somewhere. we can save users any trimming through cutting to 6mm wide-- the width of the edges of the mountplate. one sheet = 300 30cm strips 6mm wide, giving each user 6 5cm pieces they can cut to length with their razor. Then there's no tape trimming to do when attaching. * Scrapbooking tape strips: (hard to find but good size -- big lots available on ebay: is 3600 strips for $65, or 2c per strip)
