They were heavier than I thought they would be, which is probably the waterproof backing. They were also a bit uneven in size. I guess it doesn't matter if it's 92x97 instead of 95x95 if you are putting it on a bed, but in a cage it can matter. Only two were off sized though and I'm planning to have two for "cuts" anyway as I bought 6 and need two at a time. I will cut the wings off tomorrow and wash the ones I'm not currently using.
