I make picture frames, however, they've not been for scroll projects. I don't do portraiture scrolling. I'm more of a general woodworker than a master scroller like so many of you. Still I consider picture frames to be something fundamental to woodworking. The frame should not 'steal' the show but should direct the viewer to looking at the framed object, whatever it is. And the frame should project the object, if needed. And it should blend in with the colors and styles where it will hang.
Here's a couple I've done. The first is cherry with maple splines, for Swedish lace with two pieces of glass suspending the lace. The second, brush painted poplar, with acrylic over water color . A larger frame (about 30" x 50") of an oil painting, the frame is walnut and the inner portion is covered by fabric (mod podged onto the walnut) no cover, it's oil. A red oak and maple frame over a litho print, glass cover. Finally painted pine frame over a large photographic print with a glass cover.
I generally route a profile and then use a miter jig to cut the corners. I've posted about it at some point.
