Stitchery Tape, 180-foot roll
One of my favorite tools -- this handy roll will last a while--it has 180 feet on it. This is what makes your finished work lie perfectly flat forever. Super easy to use and archival, so it will never yellow.
This transparent double coated adhesive tape is specifically designed for mounting stretched needlework to art boards, foam core, etc.
Adhesive will not bleed through or damage fabrics. Acid free, archival quality. Safe for delicate fabrics. Roll is 1½" wide. Packaged with instructions for use.
