This was a delightful wedding project - and very trendy. Chalkboard signage at the wedding reception. These boards are large - 24" x 36" for the board and then add frame size.
Insider tip - I did the layout on the computer and then enlarged it to size. I was then able to complete it in one attempt. Chalk is not as predictable as pen and ink - but I think that is part of the novelty & pleasure of hand crafted art.
