Then there's no tape trimming to do when attaching. * Scrapbooking tape strips: http://www.amazon.com/Double-sided-adhesive-mounts-12-pack/dp/B00D5WDZXO/ (hard to find but good size -- big lots available on ebay: http://www.ebay.com/itm/New-72-Packs-Scrapbook-Double-Sided-Adhesive-Strips-/321157403796 is 3600 strips for $65, or 2c per strip) ###Photos Photos of the assembly process.
