After the portfolio gets full, I add of the things to his art scrapbook. I must say though, we don't save everything. There is no way I could save every piece of paper that he brings home from school, but we save the cute art projects and some of the special things like a school bus he colored, one of the first things he stayed inside the lines and it looked like a big boy colored it.
This is not a fancy scrapbook. I use black paper and attach the artwork as it will fit in the book. Some pages only have one thing, some pages are full of things. I do try to keep them in date order, but I also try to maximize the pages so that the book won't be huge.
I do try to stick with themes if possible, especially the holidays.
And the best part is that Samuel can get his book out and look at it and we don't have to worry about messing up the things he has made. I will finish this book out at the end of summer and we will start a whole new one for him for Kindergarten through probably 2nd grade (we'll see). I can't wait to start Tyler's first book too!
