But for years I just collected in binders or spiral notebooks or sketch books rather sporadically. I bought flip files and we do the work,writing on lid, art on art sheets and when completed we slide them into the plastic sleeves. The children had great fun decorating the covers as well. At the end of the year I can bind them at our church with the machine they have that puts plastic binding on. It's very simple to use.
Some basic tips can be very helpful.
We use Mona Brooks' book Drawing With Children . Your journaling book as mentioned above. Extra sketch paper for drawing or painting your entries. I like these best for putting drawings into books because they don't leave a thick gloppy mark inside your special book. Others will do however.
