Here's a way to make your kid's day with a simple and cheap project.
 The items used are as follows:

Box (any size)
Straight edge Razor knife
Staple puller -- if needed
2 cans of white spray paint  (base coat)
1 or 2 cans of spray paint (color of your choice)
Wrapping paper or contact paper to cover the top
1 Princess place-mat /stickers or your choice of embellishments.
Double-fold bias tape
Hot glue gun & glue sticks.

Cut the box to the desired height,(leave back edge uncut.pulled out the large staples that might come in contact with the child.Then I spray painted the box outside with the inexpensive white paint.The cardboard absorbs the paint very quickly and unevenly.So I would not pay much for the base coat paint.Then when that dries,paint the top coat in the color of your choice.Let that dry.

Cover the lid with whatever you have on hand,wrapping paper or contact paper.Later on if it gets ripped,just recover with something else.

The cut edge at the rim,is covered with double-fold bias tape.I hot glued it on.
Then put your embellish it as desired.My daughter is into Princess's so I glued on a princess place-mat that I bought at the Dollar store.You could also find letter stickers and put their name onit.They love to see their name on something.It's a fun way to spend time with your kids and get them to put their toys away...at least for a little while.
