For backpackers and travelers with one bag, facilities like doing laundry using a washer and dryer is a luxury. Traveling cheap and light means carrying one small backpack which means you’ll have to learn to do laundry in hotel rooms, bathroom sinks, and other areas without a washer and dryer. You can easily wash your clothes in a sink, but drying clothes on an $10 clothesline will need some clips to hold clothes.
Instructables user br3ttb used 60 rubber bands to make a travel clothesline by soaking the rubber bands in water to make them more pliable, separating the bands into three even piles and tying each pile into a long strand, and braiding the strands together.
The only trick with using the clothesline is hanging it up. You can wrap the entire clothesline around one object and run the rest of the line through the loop (check out the post for pictures).
