Flowers with Faces
Take photos of flowers and add some googly eyes to make some flowers with faces photos. You could also add other features, like mouths, but I stuck to photos where the flowers already had a mouth-like structure.
Scrapbooking Paper and Old Maps
Find sheets of scrapbooking paper that remind you of Wonderland or old maps and cut them to fit the frames.
Quotes
Choose a quote from the book that you like and type up or hand write it. Find some corresponding scrapbooking paper or stickers to decorate it.
Keys
Using the key bookmark template, create a key and select some cardstock for the backing that you think corresponds well.
Silhouettes
Create silhouettes following the procedure outlined in the Silhouette Cake Topper post and cut out shapes to make a scene with them. If you have a die cutting machine that allows you to import your own designs, such as the Silhouette Cameo, you can create a scene in a program such as Paint and have the machine cut it out for you.
Wonderland Photo Shoot
Have some of your friends dress up as Wonderland characters and take pictures.
Scrap flower
I made this picture using the scraps from the paper teapot vases that my Cameo left behind and the petals from the red roses (since I printed the white rose template on red cardstock and so the leaves did not turn out green).
