Paper bag pockets are always fun to play with. All it takes is a lunch bag (yeah, the same kind you sent your child's pb&j in this morning) and something to embellish with- lace, images, buttons. Whatever you've got handy!
This kind of project can be addicting. I use them for all kinds of things- a thank you pocket with a candy bar and a note. How about a get-well with some tea bags and mini package of tissues? They are also really cute to use for my class kits- I've got a few examples here, here and here.
While gathering the materials for this, I ended up with a pile of goodies that I quickly turned into another half dozen pockets!
Fun, fun, fun!
