I added a pocket to the inside front flap for envelope storage. The measurements for this pocket are: 4.5" x 7". I plan to add the date and sweet sentiment to the top square.
I personally think these little binders + calendars have a lot of potential and could be a happy home to lots of things... coupons, receipts, photo storage, etc. - definitely not just cards. I can't wait to whip one up for myself... hope you are inspired by it too!
P.S. I popped this over at Wee Memories - such a simple challenge this week: Use ribbon. Tie a bow on and join them! ;)
