Why not encourage your kids to collect something free? Ashley has a sand collection from every river and beach we’ve visited.
Bill’s parents have a rock collection and written on every rock is the location where it was found. Collecting receipts, photos, pamphlets, maps, or even signatures are all possibilities. Maps are cool because you can write on them – where did you go? How did you get there? What did you see? You can paste photos onto the maps and lots of things can be pasted, drawn, or written into the journal.
