If you need a section of the "loop" side of "hook & loop", grab a square of your size. High-quality professional VELCRO Veltex brand loop material. Smooth to the touch.
The material will be cut as a square, but other ratios are possible. Just choose the equivalent linear inch size, and add a note to your order letting me know the custom dimensions you'd like.
For example, a 3" x 3" square would be 6 linear inches, and you can request that in a 4" x 2" configuration.
