For my design wall I bought a product that I thought would be really great. It's by BlockButler. It's tacky, which is what holds up your blocks, but now after a year it seems to have lost a lot of its tackiness and won't work. Has anybody else tried this and have a solution to try? I got a 6' x 6' and was over $50, so I hope I can revive it usefulness.

Wash it. Do you still have the sheet that came with it? It gives directions. I can look around for mine if you need it.

I do still have the instructions, and I will wash it, can't hurt it. I live in a very dry area and I'm sure this is the cause of the problem. Thanks
