I just ran across a new term for me. I would like to know what a block butler is. I do love this site, found it a couple months ago.

I guess you do learn something new every day!!

I bought my Block Butler about a year ago. I absolutely love it. We put up the insulated foam board and then placed the Block Butler on it. This product comes in 2 sizes: 36" X 36" and 72" X 72". It is sticky on both sides so installation is not an issue. If there comes a time when it is not tacky enough for your blocks, just spritz it with a little water. Hope this answers your questions. *s*

I've got one too - the larger one, and ditto above! My biggest problem is that it was on a wall I have near my sewing machine, and I then bought a set of drawers that had to go in front of it. I now have to get it off that wall and put it somewhere else, as I can't reach it easily now.
