Frames and mounting accessories can be very expensive. I've found a couple of ways to cut corners that still produce pleasing results. Frames are easy to find. I often bring them home with no particular project in mind. One of the best places to find frames is yard sales.
Thrift stores are also a good place to look.
It's not necessary for your frames to have glass. When I'm not going to use glass I make sure to spray the surface of the fabric with Scotchguard to help prevent future stains. I mount my projects in two different ways. You can buy mounting boards in any craft store. I've found that the padded ones work great when you have a frame that doesn't have glass.
