Or… no theme at all, just miscellaneous goodies you find. There will be hundreds of fun things to add to your book so you can collage to your heart’s content!
Bring anything you like:
Pictures from magazines, old book pages, old letters (copy these and photographs, don’t use originals) that will make your book special. Three dimensional thingies work well too, if they’re not too ‘high.’
You will be collaging the box the first day, and making the book the next day, so you will have time to find ideas (and ‘stuff’!) of your own to include.
