I bought a used field kit to work with in the off-season. Both to teach myself and for pre-season work with next years team. However, I don't have all the original dual-lock stickies for mounting the models on the mat.
I ordered this stuff (http://a.co/8maiutW) on Amazon as it appeared to be just like the squares that come with the new kits and was 1/2 inch wide so I could easily cut out new squares, but it seems much thicker and has poor lateral holding power. (i.e. pulling straight up on a model holds well, pushing sideways, not so much).
Any other ideas?
