My cutting table is 50x75 and is covered by 4- 24x36 cutting mats held down with double sided tape. For me this is perfect as it allows me to trim quilts with ease once they are off the longarm. I have a big board that covers my ironing board, this is a must for me since I starch and press all fabric before cutting and it makes pressing yardage and a completed top a breeze.
It took me a while and much rearranging to find a set up that worked best for me. I keep irons away from my cutting table because cutting mats are way too expensive and we all know what happens when heat gets on a cutting mat.
