If you bought artwork without a frame and realized after the fact that you need a frame...here is a solution. It good thing about the service is its all online and offers a variety of options. Here is how it works:
Provide the dimensions of your artwork, and then preview different frame and mat combinations until you find the one that suits best. We’ll even suggest an optimal configuration if you are unsure. The final frame is handcrafted and shipped to your door within a week. When it arrives, simply insert your artwork and mount on the wall using the included hardware.
I have not used the service so I can't vouch for it but try it out and let us know.
