Query: Super cute - BUT sooo rough!

Hello - I think this set is soooo cute and my son really likes it however I have 2 major issues:1 - The elastic on the fitted sheet are so small and weak - they don't fit well around the mattress (we have a sealy perfect night mattress) and thus it comes off the mattress very easily!2 - The material is so rough - i even washed it with downy and still - the material is very rough - my son sometimes wakes up with red marks on his cheeks - he does have sensitive skin.Not sure the desriptions of kids sheets show thread counts - but next time I'll want to try before I buy!Caroline
