Frames can be made from many different species of wood. Since the grain of the wood is cut diagonally when making coves the resulting surface can have very unique and interesting grain patterns. Two furniture styles that popularized this technique were Arts & Crafts and Mission Style. It's known as "quarter sawn Oak" which referred to how a log was cut. The beauty of this technique is that it exposes flecks or rays in the wood that created a unique grain pattern. You can see that happening with the Lacewood sample.
In addition to the composition gold frames shown on another page of my website I'm also doing precious gold leaf using traditional water gilding methods. I recieved training from Barbara Carter at a workshop taken at the Scottsdale Artists School. This process is labor intensive and begins with carving and then multiple coats of traditional gesso are applied to make the surface as smooth as possible. This is followed with clays to create a base for the 22 karat gold leaf.
As an artist I'm sure you'll have some ideas as to what a frame should look like to enhance your artwork. So that you and I can collaborate and come up with the best possible frame, please use the contact information to let me know what you have in mind.
