Sounds like you're just ahead of us in the Story of the World. My kids are not too into the "crafty" projects (though we did build a sugar-cube pyramid). Or maybe I'm just not so into dealing with the mess. Probably a bit of both, actually.
Hilary, we try a lot of the crafty things because First Son seems to enjoy them, but it's not unusual for them to get side-tracked and improvise during a project or fail to show interest in returning to a project to finish it. Our ziggurats are sitting half-finished in the laundry room and I'm very tempted to just throw them away.The good thing is, I think seeing them in three dimensions did help the kids have a better idea of what they're really like, even if they are rather small.Mostly they liked mixing the paint.
Comments make me happy; thanks for speaking up!
