Hello. Last season was my first show, and for short amount of planning and supplies it turned out well. Of course knowing what I know now, I need to plan earlier for expansion. I definitely want to do a window matrix or two. I see the pre-made matrix panels on different sites for sale, but what would be the problem with using regular peg board from Lowe's or Home depot to get the same results? I know I would have to drill the holes a little larger, but wouldn't they serve the same purpose? Thank you for your input.
