I use painter's tape to secure my teflon sheet to the table. Doesn't affect the slipperiness at all. Note I said "teflon" sheet which I bought from ebay as a baking sheet. It is brown colored but that doesn't matter as much as how easily your fabric glides on it. I got five sheets for $25! That was several years ago when the original Supreme Slider came out that didn't have any tacky back.
