I have a hook up for Coroplast...I can get a 4'x8' sheet for $30..good price? The only other hook up in town is $50 and has to be ordered. I figure that 4x8 will give me enough to do both the bottom and the balcony of the 2x3 cage...trying to get hubby to let me just do a 2x4 and put it under the TV in the living room.
