I have a memory-foam mattress topper that looks pretty beat up. Originally I was going to throw it out, but now I’m cutting it into dog beds instead. From one mattress, I have enough for two 42″ crate beds, four 30″ crate beds and a leftover ~22″ square. I’m going to cover them in some leftover heavy cloth from a previous sewing project that I never actually made. I’ll be keeping a few for my pups and donating the rest to the rescue I foster for! Pictures once I’m done.
