Something I made for my GD. I cut up a badly made dress - it just happened to be pieced. On the long side I put some handles straddling the center of each side - then I put a loop on one side and an old spool on the other side - between the handles - lined it. Lay it out flat to play with little toys. When ready to put it all away, you fold the sides in thirds then grab the handles and hang it up.
To play with the toy toter open it up and play - nicely defined play area.
Fold one end in thirds.
Then the other
put the spool through the loop and pick up by the handles - less than 30 seconds to pick up the toys.
Use some ugly old double knit polyester, an old towel, canvas with roads drawn on, that ugly quilt that didn't turn out, pieced blue jeans, something pretty with lace edges, what ever works for you - any size.
