In September I took a minibook workshop at Studio Calico called Details 2. Tina Azmus did an awesome job and I thought the whole thing was so inspiring!
In one of the lessons she encouraged us to make at least 6 water color background cards and this might have been my favorite lesson. We worked from our own moodboard. You can see mine below.
Here are a few of my pages. I used book rings and my book is made with 6x4" cards.
