i would paint the top and add glass over it. For the fabric not rbibung your legs, why dont you use dowels or cheap drapery rods bolted to the underside of the table. Hot glue then sew/witcherystitch/hot glue your fabric to form a pocket to slide over the rods. use 2 separate pieces of fabric on the longer sides so you can simply slide the curtains to the sides- as you would open drapes- for when you are using the desk. This will also allow you to pleat fold, gather etc the fabric to your liking. Also, to disguise the gap (if there is one) between your fabric and the side of your door- you can add either a fat ribbon glued to the door sides or use a long, thick piece of your fabric. Or you can add a ruffled top to your fabric to cover the gap.cant wait to see!
