I am finally getting the materials together to build a C&C cage! I found Coroplast at Home Depot- but they only have it in a 3'x6' sheet- not big enough! BUT... I was kind of shocked when I saw it for the first time! I really had no idea that it was that flimsy! Is that right? I was worried about the weight, moving it, making it into the cage bottom- but if this is the right stuff, it's ultra light and seems easy to work with! I'm checking with a local sign shop on Monday when they open about getting larger sheets as I want at least a 3x6. I have 4 sows and 1 is ready to have her (surprise) litter any second now and I'll be keeping any females, so need a LARGE enclosure! ALSO, has anyone ever used clear packing tape to attach the sides if the Coroplast isn't big enough to score and fold? Thanks in advance, Lydia
