Dust free is the key here.
What I do is develop the films after everyone has gone to bed, and hang the films to dry in the shower or over the bath.
Bathrooms usually have the losest dust count because of water vapour/steam which constantly catches dust and "drops" it out.
Close the door (so that the cat can´t play with it...they sometimes like the smell or taste!) and make sure you get back to the bathroom before anyone takes a shower in the morning!
PS...a clothes peg fixed to a line, and attach another to the bottom end to stop it from curling up...works fine.
