We were inspired to try our hands at making this DIY pelmet, after seeing this post on Little Green Laptop. But if you want see some handy step-by-step photos, check out Hi Sugarplum! is actually take on the project.
What you'll need:
fabric, foam core, thin quilt hitting, ribbon, Fabri-Tac glue, 5-Minute Epoxy by Devcon, duct tape, two light-weight L-brackets, straight edge/ruler, scissors, shears, X-acto knife, iron, two small C-clamps (all available at craft or hardware stores; see below for materials measurements)
To determine size of pelmet, measure window, and eyeball about how wide, high, as well as deep you'd like pelmet to be. For our 60" high, 37" wide window, the actual pelmet was 16" high, 40" wide and 7" deep.
Cut froth core to size. Use duct tape to hold pelmet pieces together; they ought to make a three-sided "bracket" shape. (Hint: If you can't find foam core large enough with regard to window width, tape two pieces together. Reinforce along the interior with a 3rd piece of foam core taped over seam.)
