A great bridal shower activity is to make a group scrapbook. Was huge hit at my sister-in-law's bridal shower. When we sent invitations we asked guests to bring any photos, reciepes, and stories they'd like to use in a scrapbook for the bride. When guests arrived they flocked to the scrapbook table. We provided paper, tape, stickers and the scrapbook itself. The bride took home an amazing scrapbook and the guests weren't bored to tears at the shower.
