A floater frame is designed to make the painting appear to float within the frame. The frame molding does not wrap around the front of the painting and is usually flush to the face of the painting. It has a sleek modern look. I prefer a floater because I usually want the edges of my painting to show.
Consider a floater frame if you want a contemporary look that reveals the edges of the painting.
I have not personally experimented with floater frames from the below stores. Please let me know if you are satisfied with your purchase.
