I bought a Tri-fold Foam Display Board at Target for about $10.00,which measures 36X48". The center of it is 24" and the 2 sides that fold out like a side by side fridge, are 12" each. Because of the way the sides close up to 24", it fits perfect in 1 of the spaces that we tend to forget, behind our doors. And again because of the way the sides fold out, I can use different colors of felt, to get a better idea of how my work will look with different color backgrounds. The center larger piece I left white. Once done, I just fold the 2 sides in & close the door, or in this case open my door & it stays in place and out of the way. And I am utilizing wallspace that I would normally not use, nor using up space on another wall that I could use for something else, like thread holders,etc.
