There are so many ways to make mock hobbled valances! I've looked back over my photo archives and discovered that if I've made 30 of these, I've made them 30 different ways. But this one, for Paris Interiors, is my favorite method, so far.
What I'll do differently: this method took a little more time than it needed to. The horizontal rows of stitching worked beautifully but since they're covered they didn't have to be those dainty back-stitches- the job could have been done with a larger, quicker running stitch. I really didn't have to interlock the interlining at the top trimmed to the board edge; it could've folded over the board. I pressed the bottom hem ahead of time and then had to adjust it because the folds turned out a little smaller than I had expected so the bottom row was too wide; next time I'll fold it in at the end. And next time I'll use Domette for an even more substantial look.
