Paint the wood, ignoring the ends, and let the paint dry – stand the wood on unpainted ends. Glue the 25-inch length between two of the 30-inch lengths making a giant letter "U" that is uniformly 1 ½ inch thick and 26 inches wide. The cross piece should have the wide side down – the bottom of the U. Build a second U with the other lengths.
Glue the 25-inch dowels across the appropriate U about eight inches from the tips of the U. Do the same thing with the 26-inch length and the remaining two 30-inch lengths. When you are finish, the smaller U should fit snugly inside the larger U.
Cut the fabric into five equal sized strips -- each 20 inches long. Fold under each edge ¼ inch and sew. Make a loop big enough to fit around the beveled lengths and sew the loop. Slide the loops over the beveled boards so that all five strips link the two beveled boards before they are glued into place.
Put a wood screw from outside the U and into the center of the crosspiece. Glue the beveled lengths centered on the bottom of the U’s. When the glue is dry, put the remaining wood screws in place to hold the beveled boards onto the legs or the U’s.
Drill a hole through both U’s at approximately the midpoint. Line up the holes and put the two aluminum spacers through the holes. Put the long screws through the space and secure them with the nylon nuts.
