"Sheet Set" Plastic Bag Backpack

Is this weird?  I save plastic bags with zippers (like the kind sheet sets come in).  I usually put spare sheet sets in them for storage.  It keeps them together, and they stack pretty neatly.  I've also used them to store games, cookie cutters, and other random items!

Today, I had an idea to use one to make a camping backpack for Sunshine.  She doesn't have a backpack, and the other girls have been filling up their backpacks to use on their indoor camping expeditions.  The bag I found originally had a twin sheet set, so it is small enough for her.

1)  Use a hole punch to put four holes in a rectangular shape on the back of the bag.

2)  Cut two strips of material or ribbon for the backpack straps.  I used a 1.5 inch by 24 inch (approximately) strip.  Thread through holes and tie.

3)  Decorate.  We used stickers.  The bag we picked has a slot where the label was inserted, so we can put a picture or drawing in it!
