Seems like we all had the same idea. I was going to say cookies shaped like books. Or maybe somethine else edible with a line from your favorite book attached on a paper.
what about making a DIY "miniature book" that has, say 5 pages with 10 of your favorite quotes from literature or poetry about love. print on high quality paper and bind with ribbon. Ok, now that I have written that, it sounds like a lot of work!
I wonder if you can find "miniature" books of love poems or something? Love the idea of a book themed wedding, great idea.
I know these are too expensive for wedding favors, but just posting for inspiration. I wonder if you coudl find something less expensive but along these lines. Literary "word" magnets? or customizable magnets that you print up with quote from your favorite love poem?
First of all congratulations! Your theme and favor idea is wonderful! I believe I can help you out with the idea of a miniature poetry book or something of the sort. Please check out my website or email me so we can discuss what I can possibly do for you. I think original one of a kind poetry would be great or I have pre-written works as well. I can work within your budget to give you quality beautiful love poetry and/or love quotes.
