I'm also guessing you could get a big sheet cut up to save on cost since I'm sure pre-cut stuff costs much more than just one big sheet. I'm fortunate enough to have a table saw so methinks I am going to just buy one big sheet and go to town. I also need a multi tub style rack as I'm going to have at least 2 boas, 1 or 2 BPs and who knows what else lol.
