what about a cookie bar? just fill several large glass jars with homemade cookies. (get all of those helpers involved, by asking each one to make a different kind of cookie. several dozen a piece. and have each person bring their cookies to the shower in a large clear glass jar.) affix labels to the jars. display on table. put out little bags or boxes for the guests to fill with cookies. and make a little thank you tented card.
we did this for my sister's shower, and it was a huge hit. we made large round cookies, and put out bags that would only accomodate two cookies a piece. afterwards, i was able to use my glass jar to store flour, while my aunt uses hers to store rice and such.
