The first one I have participated in over at the Cricut message board. Had a lot of fun creating. A few of the winter pieces are in the post below this one.
The fall/Thanksgiving were fun. My extra piece is the little squirrel. I do enjoy googly eyes.
The Birthday Boy set was fun, but I think I would end up spreading out the items over two or three pages since I tend to take a lot of pictures. But, below is a sample layout anyway. I didn't include sticker pics as they are the extra with this set.
