Thanks Everyone I guess I might try the vinyl tablecloth. It can then be rolled up and put out of the way.
In order for me to photograph my last quilt, about 110x80, I had to purchase a long curtain rod with rings with clips, so I could hang it. Only place I had open that was big enough was the entrance between my kitchen and living room.
I figure I can hang the quilt design thing in the same place. I'll use the 1/8 foam board I purchased for my friends STEM class on automobiles (balloon powered car)/physics.
I'll have to price the flannel to see if I can afford it. If not, the scraps of cotton batting will have to do for now.
