I don't have a car. Actually, I don't drive. So on my commutes on the bus or subway, I have a lot of time with my thoughts.
Its often while I'm sitting in rush hour traffic that ideas about future projects pop into my head. There's a fairly good chance that by the time I get home it will pop right back out, so I got into the habit of carrying a little notepad with me pretty much everywhere I go.
My favorites are little sprial notepads by Ecojot. Perfect size, cute patterns, recycled paper and made in Canada.
I loved my latest one so much I went back and got the matching journal.
Note: Ecojot has a link on their website to their design blog. It's so cool to see the creative process before the end product is completed.
