Interesting to see all the the different methods here. I don't frame under glass as I can't afford museum glass. And the only one I did frame under glass did not draw any attention or sale at the gallery. I had it framed under non-reflective glass at first but had to have it removed and changed to normal glass as it looked terrible and make everything look grey.
I don't post any of my work. It is all transported by me so I could glass it but I really like the look without it.
Here is one that I had done recently. it has 2 frames (one inside the other). Sorry about the picture quality and the bowing of the frame but I don't have Photoshop or the skills to make it straight.
