I always buy a king "bed in a bag" for our 6' bed, I used to get them from Burdines but found this year that they didn't have much of a selection. I was also looking for king pillows but they now only stock Tommy Hilfiger which I bought last year and wasn't impressed with. I eventually found some in Beals Outlet with my 15% Monday discount worked out better than Burdines(Macey's) 11%.

Ross also has some resonabley priced sets but Beds Bath and Beyond normally has a bigger selection.

Missy you can find both stores at the Loop, cnr of Osceola Parkway and John Young Parkway. Plus Michaels for the crafting.

I'd also go for a Queen instead of a full size. You can get "sheet suspenders from the pound shops here to make the fitted bottom sheet snug if needed. They might also sell them in Dollartree.
