User questions & answers
| Question: | How many come to an order |
| Answer: | I would describe it as more off-white. It is not the same color as the frame. The frame is a very crisp white and in comparison the mat looks very slightly beige/off-white. Looks very nice! |
| Question: | What are the dimensions of the clamp part, excluding the handle |
| Answer: | So, Unfortunately probably not. I do Like the frame.. look and quality are good...but I had a canvas photo I wanted it for. I actually had to take it off of the wood and just put the canvas in the frame, otherwise it was too wide and wouldn't lay flat on wall or hang right. |
