I keep a notebook that lists each scarf or piece of fabric that I eco print. I note what the fabric weave and content is, the mordant I use and of course the plant matter used. I try to go back and make notes on what worked or didn't and if I decided to do any over dying as well.
The old notebook was "as is" from the store. It had flaming blue butterflies on the front and had quite a collection of neon green Post-it notes sticking out of it. Not too attractive.
Now that it is time for a new one I decided to be more intentional about it. I used hand made papers to back up one of the eco print papers I did last year. I may even buy a high class pen to go with it. It will be a lot more pleasant to scribble in this one for the next year or so.
