This is kind of a hokey post but maybe other Artists will identify with it. I've always liked the excitement when I've finished a sketch or completed a final piece, to see what it will look like in a frame.
I often use a frame I have on hand to envision what the work-in-progress will look like when it's complete. So, when I found this resource online, I was thrilled. Pictureframes.com is where I get most of my frames and I recently discovered that they offer a service that allows you to upload your art, choose a frame/size, and see what the two look like the together. It's sorta of a try-before-you-buy service. You can even enlarge the final sample and save it as a .jpg for use in promotional materials, websites, blogs, etc. The samples shown above lets me or my client see what the paintings will eventually look like in some of their ready-made-frames. Give it a try. If you are having trouble, leave me a comment and I'll walk you through the steps.
