Woodware 3mm Foam Mounting Tape. This tape is perfect for mounting small items, much easier than trying to cut up pieces of wider foam tape. The tape is 3mm wide and 3mm thick and comes on a 2 metre roll. Just cut it to the desired length, apply to the item, peel off the backing tape and press into place. The tape double sided, acid free and non staining. The ideal way to add dimension to your hand made card designs.
