I almost always make larger quilts - some are twin size - most are double or larger. I have a glass top dining room table. I clamp the center top of backing,batting and quilt top, I pin all this and then move to one side, then other side,then top and then bottom and move however until all is pinned. I have never used the floor. To creaky to get down on knees. Am going to buy bed raisers to put under table legs to raise it. Easier on the back that way. Good luck !!!
