Handmade Checkers Game - final board stamp

I´ve recarved the checker board linocut ocean waves stamp and this will be the final one. I want to print ithe checkers board now, but my fabric is 2cm too narrow. Argh! I´m thinking of lopping off half an inch on the edges of the stamp just to save another trip to the fabric store...

I´ve also tested the setting and washing of the paint. I read on the internet that just putting the fabric in the dryer for half an hour on a hot setting would set the fabric paint. Not so. All the paint washed out. However, the traditional two minutes ironing does set the paint OK. [I´ve since finished this game here].
