KONOS has wonderful timeline figures and a nifty, hard-as-nails, plastic timeline wall-chart that you can hang on your wall. At one point, we had our big white and blue timeline in the children's room... and then it was banished to the garage (where it didn't get used as much last year). After our move out of state (and out of a large house into a small apartment) the timeline is collecting dust; rolled up in a closet. There is hardly a wall for furniture to back up to in our little abode, so we certainly have no room for a large wall chart. I really pushed to get my better (and possibly more sensible) half to allow me to hang my laminated wall maps we got at Sam's Club this summer in our bedroom/computer room. A card file (or even a notebook) seems the legitimate next step for our needs (we've missed using the big one this year).
So, if you are looking for ideas on how to build a timeline, please stop in at Timeline Helps for tips and wonderful photos (for visual learners like me).
