My sister made some gorgeous decorations using book pages, including bunting, signs, table runners and platters. Details and links for some of the decorations are below.
I also did some other bookish decorations including Alice in Wonderland/Through the Looking Glass, Harry Potter, Dr Who, Peter Rabbit, and Peter Pan. I also used the Once Upon a Time theme throughout.
Food included all of the usual party fare such as pizza, wraps, sausage rolls, fruits, meats and cheeses, and a dim sum selection. My Brother-in-law and sister made some yummy desserts, and my friend brought some Harry Potter cupcakes. I threw together a mudcake at the last minute because my hubby thought the grandkids might enjoy singing "Happy Birthday". We also had far too many sweets including chocolate frogs, pirates gold, Jack's Beans, the Evil Queen's hearts and Golden Snitches to name a few.
