Now - I disagree with donnajean. I have a sliding closet door ($15.00 at a recycle place) on 2 2-drawer file cabinets ($5.00 ea at garage sale). DH just cut it down to 36 x 70. I like the extra room for laying all my fabrics out ---- and my pattern, cutters, rulers, marking pens --- and my JUNK! The size should be determined by how much room you have!
