How to make canvas wall art for your room

I found this online, I want to try it out if I can find the right fabric to go with my new black and white bedroom set!

Here's how to make a giant piece of wall art for your room.

Choose some fabric with a large-scale pattern. Go to your local art supply store and buy 4 lengths of wood frame made for stretching canvas. The wood strips have corners designed to interlock. (Or you can cover an existing blank stretched canvas, but it will get pricey if you go very big.) At my art store these wood strips were standing in bins, available in lengths all the way from super short to too long to manage. I bought 2 each of 50" and 34." Each piece was a couple bucks. Push your corners together, pounding them with a hammer if needed. Cut your fabric to a size somewhat larger than your frame; you'll need enough to wrap around to the back. Iron your fabric.
Position your fabric the way you like it, and use a staple gun to tack it down. Stapled all along a long edge, then did the opposite side, pulling it very tight. Next do the short sides, one at a time. Cut off any extra fabric that hangs over the edges of the frame. To finish the corners, just sort of tuck in the extra as if you're wrapping a present and staple it down. Doesn't matter how you do it as long as it looks tidy from the front. Attach a picture hanger (or maybe two if your panel is large) and hang. Note: This fabric is Pernilla from Ikea.
