I found a tutorial on You Tube that a lady made a table out of styroform insulation. I liked it because you can cut it so you have a flat surface on which to sew. i got a 2 in and a 1 in thickness at Home Depot and my husband showed me how to use jigsaw to cut the opening. I traced around my machine and I put a piece of vinyl over it so fabric would slide. I now have a 5X4 ft surface on which to quilt. I love it. You can make it any size you want. I have mine on a portable table from walmart.
