I go to a lot of retreats and get together with others to sew. Have the wool mat for embroidery. But for quilt pressing we took an Oak TV tray layered with multiple layers of cotton batting then covered with cotton duck fabric and stapled the fabric to the back. Videos on UTube of this. I even took some regular cotton fabric and put some elastic around it as a cover so I could wash it. Now we have created something larger. We took one of those small plastic adjustable tables and my husband cut 1/4” plywood to fit the shape. He used small screws around the outside edge to hold the wood to the plastic top. Just use an travel ironing pad and an old tablecloth thrown over it for pressing and the wood surface keeps small cutting mat in place for trimming blocks
