For those wondering if the teflon oven liner from Wal-Mart works (Mainstay brand) - Yes!! I picked up a sheet of it yesterday. Put some of the rubberized shelf liner on the underside (so it doesn't slide around on my table), cut out a small space for the needle. Got the idea from this board yesterday (believe the original poster had purchased her liner from Bed, Bath and Beyond - it was $19.99 there, the sheet I got from Wal-Mart was $10).
I was not going to be able to FMQ on this new sewing table because I couldn't move my quilt around with ease (I do use machingers). Difference after laying down the teflon liner was night and day. Made me a very happy camper.
