our grandmothers used their beds but I have used tables (12ft long and several together) to make my quilt sandwich. I tape down or clamp down the backing and carefully add the batting and clamp or pin that to the backing and add the top and pin. I have been successful with this method. Many churches and quilt shops in the area will allow you to used their space without cost. Check in your area-also quilt guilds can tell you where they have space available for large projects. My last quilt was 120" square (special request from DIL) and I didn't have any problems with puckers.
