If you didn't see it, we were discussing the topic here:
You have got to try this vs clamps or tape.
Well, lo and behold, looky what I found at Bed, Bath & Beyond today! Sheet Smoothers - Long Sheet Straps. These are made to go from the head of the bed to the foot, to hold on the sheets. But they would be awesome for quilt basting too, for those who can't use clamps on their tables! I'm going to try them out and let you know how it works. Pretty pricey at $14.99 for 2, BUT I used my BB&B coupon so I got 20% off. They are length-adjustable too so if your table is small or large, I imagine they would work for either.
