Nautical theme thank you favors. but maybe have it say "tank you!" I'm not a fan of party favors, they're redundant in my opinion, but the mint life savers as part of the baby shower would add a nice touch for the theme.
nautical themed shower: nautical favors- This is a really cute and inexpensive idea. I can bake up some cookies or brownies the night before (has Michelle mentioned that I LOVE to bake?) and I could package them morning of the shower.
