Stitchery Tape aka Framing Tape
This transparent double-coated adhesive tape is specifically designed for mounting stretched needlework to art boards, foam core, etc. One of my favorite tools -- this is what makes your finished work lie perfectly flat forever. Adhesive will not bleed through or damage fabrics. Acid free, archival quality. Safe for delicate fabrics. Each roll is 60 feet long and 1½” wide.
Add a set of acid-free foam core boards!
