Such a smart idea (feed old book pages through a printer to make unique silhouette art). Not gonna lie, I'd probably scan in the old book pages first, and use the scan for the final print. I love my old books, I don't want to cut them up.
Neat DIY idea for decorating baby's room – except in the empty frame I'd hang lettering that spells out baby's name. This gives me a great idea for a gift to make for my brother and sister in-law to congratulate them on their new bundle of joy!
