been there, done that, my knees and back will never forgive me!
I invested in two 8 ft. folding tables for about $80.00 each. They always come in handy when we have company over so I had 2 excuses to buy them. they aren't wide enough to do a whole quilt at once so I tape the part that fits and hang tablecloth weights on the sides to keep it taut will I layer. works very well
