Called 1 inch Binding Tape (non-adhesive).
Use this 1 inch wide
paper-thin, highly flexible form of webbing to add a professional
touch and added durability to your bag or pack. Heavy, high denier
fabrics are very strong and abrasion resistant, but their larger
weave makes them fray at the edges more easily than lower denier
fabrics. Fold this binding tape over the exposed edge of the fabric
and sew it into place with high strength nylon thread. Creates a
durable, good looking edge that hides minor fabric cutting errors in
the process. Cut to order. Note: lengths over 100 feet may not be
one continuous piece. No refunds after order is cut.
