I would love suggestions on this as well. We want to do a broad wall timeline since I have young ones, but keep it simple and fun as well. I don’t want to buy anything. I like the idea of using index cards and a line with clothespins like charlottemasonhelp.com suggests, but want to have some kind of graphic/picture for coloring or cutting out as well… since my daughter likes to color/create maybe I can just have her color a picture on the back of the index card (kind of like narration of the event) and write the event on the front.
I have a long timeline on my wall from Knowledge Quest, and the kids add their figures to their BOCs. We are using the Homeschool in the Woods figures a lovely friend gifted us.
