3/8" thick and 2" wide that have a groove routed out of each one of them on the inside surface so the the binding of the quilt is contained within the routed area and then the 2 pieces are screwed together and the whole thing is screwed to 3 molly screws placed in the wall. The mondrian is in a new quilting area that I have dedicated to machine quilting that is in the attic. The Janome is the machine there and will be used with the table shown and a machine quilting frame, to be purchased later. I decided to move that machine up there as I only use it for quilting the sandwich and it was spending most of it's time just taking up valuable space on the main quilting room. Now it has it's own place and I can come up there to finish off any large quilts that I am working on without disrupting the main sewing room while doing that stage of the process. The quilt in the stairwell is one of two that will be placed on that wall and is placed up high so as to accommodate the lower placement of the second quilt. I am quite glad to be finally getting around to hanging up quilts on permanent display, that had been just sitting around and not being seen in their entirety.
