You can buy some really great clotheslines for kids- here is one from For Small Hands (not a paid spot, just like their products)
We just made one real quick with what we had:
I placed the clothespins in a pail and some cloth diapers in a basket next to the line. We may set up something more permanent outside that is kid friendly when I get a chance. For now, we'll take down the string and keep it all in a basket on the shelf.
(yes, he has the same shirt on as monday- it's a soccer day and apparently we HAVE to wear it all day if it's a soccer day....)
