Sorry, no pictures yet but I can answer a few questions.

Q.When you described using stretcher bars, you stapled a piece of fabric to the bars, and then stitched the quilted piece to it.  Why not just staple the quilted piece directly to the stretcher bars?

A.You don't want raw wood  and its acids touching the actual quilt. I often just fuse fabric to the bars rather than staple the quilt. This will give me something to sew teh fabric to. I tend to be picky about the back of my work and think staples can look ragged. That must be the result of my traditional quitling background. Also, I wanted some of my small pieces to "float" in front of the wall. The bars are  smaller than the quilt so you can't see them unless you put your face almost to the wall.

You can, of course wrap the quilt  around the edges of painted or varnished bars and staple it on. Then the quilt itself is  "gallery wrapped." It's a very nice presentation if you carefully cut away the bulk under the corners. You can add a strip of fabric to the sides of your quilt if you are squeemish about stapling into your quilt.

A good friend, Christine Hager-Braun just wrapped her quilt in an interesting way. She purchased jewelry chain from the craft store and attached it to the inside of the stretcher bars with U shaped staples/nails. She then sewed the quilt around the bars to the chain. Clever.
 

Q.You mention that it is easy to make your own stretchers using 1 x 1 lumber.  Can you provide a little more detail?

A. Miter your 1x1 and use wood glue and clamp the corners. When the glue is dry nail the corners together if you don't have special framing tools. You can also buy canvas stretcher bars at an art supply store that just fit together with slots on the corners.You will need to then seal the wood in some way if your quilt is going ot touch it.
