[ Photo from Sleep Better ]AT reader Stephanie sends us this question: I have a 2" queen size memory foam mattress topper I'm not using anymore. I've thought about cutting it up, but i have no idea how well it would work. It seems like a waste to just throw it away, but I'm at a loss for what else I could do with it. Any ideas? Dear Stephanie, Hmmm...this one has us a bit stumped. So, this afternoon, we stopped by our nearby yarn shop and posed this question to the resident crafty ladies. Their advice? You could cut it up and use the foam as pillow stuffers, or create a NASA-inspired pet bed from the material. We're thinking that it might be worth holding on to it, as it may come in handy when you have overnight guests. Or, depending on how used it is, you could always sell it on Craigslist. (We know a grad student who recently plunked down $40 for one off CL.) Anyone have any other suggestions?
