I went to the hardware store and had them cut a piece of Plexiglas for me much larger than a Supreme Glider for a LO less money. Have your Daddy In Law look at a pic of the SG and then cut the hole that you need for your machine. It is easy to move out of the way when you need to and much sturdier. Get the thinnest Plexiglas you can get. HAVE FUN!
