Next year I will likely forget the ideas I tried this year so I'll blog about it just for my own records. :)
I bought gift boxes from the dollar store (the smaller ones were in a multiple set for a dollar!) so that I'd have 24 total boxes that I could fill with books and crafts and such! Each day the girls got to open one and the first few weeks this was absolutely wonderful, but it did get a little old in the week leading up till christmas. I might do a 12 days before Christmas or something else to make it shorter. Maybe just week days and not weekends? I don't know, it needs more tweaking. :)
