Gauche Alchemy is an ArtFire store I found on Tonya Boone's blog this is corrugated cardboard in 12x12 size that is used for scrapbooking/card making.
I have been looking for this so that I wouldn't have to hunt down a cardboard box to get a piece and then have to remove one side of the paper off of the corrugated middle and not to mention it is 12x12 and I can use it as my background on a layout.......
Corrugated Cardboard 12x12 Sheets
12x12" sheets of b-flute cardboard, thin and light, corrugated on one side, smooth on the other. For use in card making, scrapbook pages, tags, mixed media artwork, art journaling... whatever you can dream up!
I think I might be inching out of my rut and maybe my scrapping mojo might be resurfacing somewhat I am organizing my scraproom at the moment and I am going to Home Depot tomorrow to pick out some refreshing new paint to re-paint the walls. Right now the walls are painted cappuccino and it needs a face lift..
