Dina - great instructions! Because I don't have any walls to dedicate - and I am still new to quilting - I was playing with the idea of smaller foam boards (from the Dollar Store), cover with a light batting, and then some flannel (as you have) - and that would give me smaller - more mobile boards to work with. (I am always re-organizing my space - I think it is a hobby!) :-)
