Hi Rolland,
I am not shure how you are framing your work... I only made canvas available to my clients if they ordered 16x20 or larger. Once the prints were made and stretched, I had some frame choices for them to choose from. These were generaly the thick gold types of frames that you normaly see with oil paintings etc... these types of frames easily accomodate stretcher frames etc... My town has a wholesale art warehouse where I can purchase pre-made frame of this type for much less than can be bought at a craft shop. Oh well, I hope this is of some help to you. BTW, I no longer offer canvas in my studio. Though I do some weddings, our main stay is B&W portraiture and the largest that we print is 12x12" Good luck with everything!
