We made home made bit and bites last year and then I bought big sealable jars from the dollarstore and we made a card to go with it. We painted baseball caps one year, we have made t shirts. You can fabric paint on the cloth tool belts from home depot.
We have decorated mugs from michael's one year. There is always decorating a picture frame and putting in a candid daycare shot, to put on their desk at work. We might make granola for the dads this year, or cookies , my father's seem to really like the snack themed gifts.....
