Here isa simple solution, for the mysteriously abandoned socks. Children will love to play "Hot Potato" or any other kind of imaginative game and if they are like my nephews will end up trying to swing them at each other in a game of tag!.
Materials: Unmatched socks
Fill the sock with about 1 cup of dry beans or rice.
Tie the end and pull to tighten or like I did; you can fold the edge over cut off any access and sew it shut
