Bought the cards - like the small format
I thought about printing my own, and then decided that my time was better spent on other projects. I ordered the cards and have found them helpful.
The size is perfect. They fit nicely in the NoteTaker wallet, but aren't so small that I lose them in my in-basket. If I had an easy way to print on this size card stock, maybe I'd tweak the layout a bit, but I'm happy with my purchase.
I've found that forcing myself to fill out the context, priority, and due date at the time I make the note is very helpful.
