Called around to sign stores today, for the coroplast it will be $20 for a full sheet, and I'll be taking my hubby with me tomorrow to pick it up! (He has a truck) And we're leaving here in a few minutes to look around for the grids! I was going to do it all in pink and brown (brown coroplast and pink grids) but those grids were $40 and I'd have to buy 2 packs and pay shipping LOL. So that idea got shot down. So it'll be black and white, black coroplast and whie grids. We'll also be going to the dollar store to stock up on towels, and the fabric store for fleece! lol
