oh i was wondering about this too cause my mum bought me a tumble dryer for my baby shower but i havent even used it cause every single baby item i have says do not tumble dry!!
i have washed all bubbas 0000 and 000 and just put bright colours together, then the next load i put the pastels and whites together and nothing seemed to run or get ruined....damn wish i knew they woulda been ok in the dryer, now they all have lil peg marks on them
