If you have the space then go for it. I have a cutting table, etc that is 46" x 46" with a leaf that folds down that is 46" x 22". I ordered a custom cut mat for the large side and had then ship the left overs and my DH cut those to fit the leaf. It is great. I would post a picture but not where I can get to the file.
PM me is you want a picture and I will send it later.
