Hi Linda

Thank you.
I'm not sure you can go much lighter, it already looks pretty light. But if you go to an Annie Sloan Chalk Paint distributor (check on the internet who sells it in your area) you can see the actual colours and decide for yourself, and they might be able to advise you if you bring the small drawer and your BM wall colours samples along. You might choose to go with a darker colour for more contrast if you're going to sand off some of the finish, or stay within the same family for a subtler effect. Here in Montreal there are 2/3 places that offer classes to show you how to do it yourself.

Thank you for sharing your gorgeous project!
