My hubby took a 18x18" board (plywood or chip board), covered it with batting and then with fabric. We duct taped the batting and fabric on. I use it all the time. We made me a longer one.....28" long, but it's too clumsy for me to use. I had a big 3 foot by 3 foot one on my table and LOVED that. I donated it to my quilt group when we downsized and went on the road RVing full-time. I like the SOLID feel of it.....the blocks press nice and flat.
Oh.....and CHEAP!
