Currently I'm creating a bunch of journals, small ones and bigger ones. The basis is always a composition book. I usually start with some papers and from there I see where it will take me.
Here are two mini journals that I just made. The different papers come from the same daisy d's paper pack (that I bought several years ago).
I like this small size for a journal because you can take it pretty much everywhere. It even fits in the back pockets of your jeans. Or in your purse - it's smaller than an iPhone.
I'm linking this to Art Every Day Month for day 8.
