The Architecture Journal has a mix of watercolor paper and lined OR grid (your choice!) The mix of papers makes it so handy to sketch or watercolor the architecture you are studying on one side and narrate on the other side! (The middle page is fully lined).
A note about the company: Juniper Grove Journals is a very small family business. Brad and Micah and their children Kate (13), Olivia (11), Maggie (10) and Jonah (7) all pitch in to make the journals from scratch. Micah designs and manufactures the journals, while Brad designs and prints the notebook inserts, and the kids bind the inserts at the kitchen table. (True story - The only rule is that everything has to be cleared away before dinner. =)
