I think you definitely should show all four. I don't know a quilter who doesn't love show and tell. I just can't figure out why your guild has a "line". At ours we just ask for S& T from each long table, one at a time, and no one has to stand in line. We just take turns standing up with our quilts when it's turn for those at our table. I think your guild should come up with another system so there's no show and tell line. Who wants to stand in line holding bulky or heavy things?
