I use a journal to keep track of my projects, record what I've done, and design new projects.) Usually a design page includes sketches, notes, yarn samples, and eventually a copy of the ball band from the yarn I used and a photo of the final project. This page is a typical example; it's the design page for the Cupcake hat I made recently. It's a rare occasion when the finished object came out very similar to my original sketch -- you can see the sketch here, and the only difference, really, is that the final hat has no flower at the peak, and alternates pink and yellow flowers. And the name of the pattern changed, because I thought the finished hat looked like a cupcake.
I also included a clip of the flowers from the reference book I used to make them, and photos of the first draft hat and the final draft.
The journal is the Stitch 'n Bitch knitting journal, which is not bad, but the binding is lame and there are not enough pages for finished projects. However, I'm repurposing other pages for that. I do actually love the journal other than those small problems.
