Ideas for wall hanging pajama bag

A friend of mine is needing some kind of a bag to hold her daughters pajamas in so they do not sit on the floor.  Her daughter likes to wear the same pajamas for a few nights in a row, so my friend though this would be a good idea.  She is wanting something she can hang on the wall.  She was initially thinking of a drawstring bag, but I am wondering about something that would stay open for easier in and out. 

Does anyone know of a pattern, tutorial for something that they think might work for this purpose?  Or even a picture/idea for something?

Thanks so much!

I don't know of a drawstring bag, but we like this pillow which has a pocket just for stuffing your pjs:
