I've never owned one. Occasionally when I get snowed under I'll take a load of towels down to the laundromat to run through the dryer. 99% of the clothes we have say "do not tumble dry" on their tags, yet I hear so many people who seem to use the dryer for everything. Are there issues with doing this? Do clothes shrink? Are there certain fabrics more prone to shrinkage in the dryer - flannelette, track suiting, t-shirts?? TIA
