I've been keeping a monthly project tracker since February and it's made a huge difference. I've stopped losing track of what I was working on just before whatever happened to distract me happened...and that means I'm much less likely to start and abandon a new project. I can also look back and tell when I started and finished things.
Right now, A Little Girl's Fancy has a blank column because I'm letting it sit while I stitch on things I'm more excited about. The constant reminder that it's there is going to make it harder to forget (although I reserve the option to just not stitch on it until the urge strikes again.) Nothing I started before the tracker is listed, but I'll give those projects a column when/if I pick them up again.
Next goal -- better project bags. I need some for the shawls that are big enough to hold the project and pattern AND all of the skeins of yarn I'll be using. Stopping mid-row to hunt for yarn is a pain.
For now I'm just happy that everything in the planner is also in a bag and they're all in the same place.
