Update: 8/9/13 I've enjoyed working on this but after having completed 46 of the 72 alterations, I think it's time to give it a rest for a while.
I've been working on this journal since I got it last week and am having so much fun with it! I'm a perfectionist, so it's a bit hard to just do the alteration process but I'm trying not to second guess things too much and just go with the flow.
I'm not working on the pages in order, just filling them in as I find the instructed items. Also, you're supposed to flip the book upside down and randomly open it to pick the alteration but I wasn't keen on that so DH created me a random number generator in Excel that marks off the numbers I've already used. I think that the chance element of the exercise means that you could (and probably should, if it came up) do the same alteration twice but I prefer to do something different each time. Definitely helping me branch out creatively and be less concerned about a "perfect" end result.
