Just finished making my own Addy's School Supplies set! The satchel is made of leftover fabric from my Kirsten's Summer Dress project, the slate and reader are made from paper and cardboard scraps, and the slate pencil is made of duct tape. The abacus I made out of Popsicle sticks, bamboo skewers, and pony beads. I copied the reader cover design as best I could from the AG Wiki page. I will try to do Samantha's set next.
This picture shows how it all fits in the satchel.
