I love this idea. An envelope guest book. You just take a store-bought scrapbook/album and glue envelopes into it. Lay out colored pieces of paper for guests to jot notes down on, and then they can place them in the envelopes.
this would be a cute idea for some homemade stationary for the missionary to use along with some envelopes and stamps.a heart cut out from the area s/he is serving in.not sure about the text though in the front.
