You should mount it on top of a mat to allow the deckle edge of the paper to show, then have another mat to keep the glass away from the paper. A narrow black frame would go well with the artwork. Do you still intend to keep the other pictures above the fireplace, or will this one replace the three?

I would go to Hobby Lobby and get some help there. They have framed a lot of my artwork, and they have pointed out ideas to me that I hadn't thought of. I'm jealous of your window seat.

There is a site called pictureframes.com. You can load a picture of it and try out different mats and frames on line. I was going to do it for you but it asks if you have the copyright for the picture so I didn't :)

what a lovely piece of art from your daughter!

Thanks Suero for the suggestion of showing the edge of paper. I plan on just hanging the new picture. Maybe something like this pic??

Thanks Boopadaboo. Great idea. I'll give it a try.
