I also use the lattice panels to display my potraits. Instead of framing all of my work most of it is in page protectors from an office supply store. This eliminates having to stock frames and I can store the portraits in notebooks. I use drapery hooks to hang the portraits from one of the holes in the page protector. If you use the hooks grind or file off the sharp point.

The panels hang from my canopy for outdoor shows. For an indoor show last year I made a simple frame out of 2x4 lumber to hold the panels. I measured how high I could easily reach and that became the height. The length was determined by booth space and panel size. My booth space was 7x10 not 10x10. I assembled everything at home and marked all the pieces before taking it apart. Having the peices marked made assembly at the show easier.

Hope this helps
