I bought GMC a set of black sheets, after a year (little more) of using them, every other week...sometimes more, there is hardly any wear.
[I also have for his bed a set I used when I was a kid, only the bottom sheet needed replaced...the old one will be made into a pillow case

]
Anyway I bought JC a set of pinky princess sheets last..err month maybe? the second time I washed them I saw pilling, which has only gotton worse.
what should I look for to find the first set (I no longer have any packing/information on them, pitched it) quality, not the second? they both cost the same...
