I recently attended a Clamshell Box workshop facilitated by Suzan Lee. I was able to construct a box that could house booklets, a special book or other precious objects.
As always, Suzan was very well-prepared and the workshop proceeded without a hitch in a great working space at Gilligan Girls in Vancouver.
Here's the box I created, made with a sleek Japanese cover fabric and Italian papers.:
Perhaps one of my future handmade books will be accompanied by a clamshell box.
