In the front of the book I put an envelope that holds the strips of paper - each with one of the 100 things on it. It's just in there temporarily right now - I'll find a better way to attach it. This way I can just pick out one item and do that project. I have no rules about it...if I don't feel like doing that thing today or this week...I just put it back and take another one. I'm going to decorate the cover and keep an index of sorts so that I can make sure that all 100 (actually 94 or 95) get done.
Here are some of the inside pages. I am not putting them in numerical order, but rather completion order, or where they can fit in the book. I'm purposely sort of chunk cutting out of my other books - uneven edges etc. I didn't want this to be a project unto itself and want the spontaneous, chunky look. I also have a few things in there that can be flipped over and attached those with paper strips with PVA glue. So far that's working pretty well.
