I love those pages to print out too....
What I just started for my 3 youngest are autograph/scrapbooks...
Bought spiral bound scrapbooks with plain white cardstock at
walmart ($1.50

for pink and $7.00 for black)
Got stickers, letters, numbers, embelishments, etc at Dollar Tree - spent around $40.00 for the 3 kids (but feel I will have tons left over of somethings and not enough of others)
And scrapbook thick papers packs at Dollar Tree in various solids colors (also have these at Walmart and Michaels for more in different sizes/patterns/colors) - we will have the characters autograph these - taking only the colored papers to the park with the clickable sharpies in various colors
We decorated the outside of the books with stickers, letters, and will put a picture of each child dressed up for
MNSSHP on the front
Inside we're gonna put the autograph on one side...then a picture of the child/kids with the character on the other - and have some room for mementos, clipart, or extra stickers...
I was thinking about starting the pages with the characters we know we will see...like Mickey, Minnie, Pooh, Tigger, Donald, etc...and then go from there as base the pages on who we are able to see so we don't try to go character hunt crazy

and find every one we printed something for
It's been a great way to pass the time so far....
