My friend has a very very limited space to quilt. And no room to spread a quilt top on the floor to sandwich. And this is what she does....
In her bathroom, she uses her shower rod and has rings that she clips onto her quilt back, then the batting and then the top. And then she will hand baste it, take it down and sew it on her machine. Pretty inventive I think. When a peice needs to be ironed, she uses one of those steam irons they advertize on TV that uses just steam and won't burn you or pop a balloon.
