I have limited space to display work on my walls. I have 2 pin up boards and am not allowed to hang anything directly on the walls. I also have plain white laminate tables, which do not really match the rest of our studio and so I solved both problems.
I bought the clear plastic from Lincraft but you find it in many places. The plastic has flattened out over time, however you could lay them out in the sun to or use a hair dryer on a low setting to smooth it out.
The students have responded well and asked for their work or photos to be displayed on the tables. They do get dirty still and some students may get creative with the scissors around the edges but I am still happy with the decision.
