What a clever idea. I have one of the purchased ones but my husband kindly replaced the plexglass when I broke it at one of my retreats. He is a machinist. Another wonderful advantage of the clear top is that I store my scissors, extra bobbins, my accessory case etc. etc. underneath of it. They are out of the way and I can see them at a glance just by lifting the fabric off of the surface. That doubles the use of your table surface. My husband also cut the legs off of my sewing table so that with the slide on plexglass surface the machine is just the right height to be easiest on my back and neck.
