On the subject, I wondered if people wouldn’t mind sharing what they use, AND how much they pay for their frames.
I get all my frames from CanvasPlace.
I use their panel frames.
They are $43 for a 6 pack of 6"x6" black panel frames.
They are very simple and you have to find your own way to attach the panels but they are effective and economical for small 6x6" paintings.
