So I'm not having a shower and this isn't even wedding related. But we got a new mattress and apparently the pillow top is way thicker than our old one and none of our sheets seem to fit. At first they go on but after one night the have worked there way up the corners of the bed and we have to pull them down each morning, it's getting really annoying. I really don't have $100+ to be spending on some quality Egyptian cotton sheets but the cheaper places (Marshalls, Target) don't seem to sell any labeled deep. Any suggestions? Thank you!!
