Hi Sandy, hope this helps you frame your canvas. How to Frame a Canvas (for Cheap!) | The Turquoise Home
This easy DIY tutorial will teach you how to frame a canvas for cheap, making a huge piece of $22 art look like it’s worth much more! ... And since this canvas that needed framing wasn’t pricy in the first place, no need to go champagne on my beer-budget art. Do you recall my DIY ...
Framing is expensive, whether you have the skills to do it yourself or take it to a framer. This painting which fills almost all the wall; ceiling to floor would be about $300 to frame if it was a home made job. The larger the canvas the wider the frame must be which is more expensive than a narrower frame. I just looked at Peggy's link and I think "large" must be open to different interpretations! Good luck.

Hi Sandy: You can use molding for your frame. There are so many designs and widths to choose from. You can either miter the ends or use butt ends, where you just butt the ends up to each other. Here's a site that shows both joints, but they're talking about floors and stuff, but you can use a miter box for your purposes and you don't need the gloves and glasses:) If you are going to miter the ends, get a foot or so of additional wood so that you can practice and get it right. Never hurts to practice:)
