thank you everyone who made a comment. In a few weeks I will be squaring up 25 blocks for my delft quilt I was not looking forward to it. Since reading this thread I have purchased a small rotating board. I do have a larger one which is too heavy to transport I purchased it 6 years ago. Looking on amazon found a 14 inch square board great.
so thank you everyone for your comments and making me look at what sizes they do nowadays. Local small shops in my area don't supply a choice but amazon is great.
