Allen + Roth is Lowes' house decor brand. Based on the names you might guess that they are a couple of old artisans, but it is more likely that it took a study from some Lowes market researches to determine that the connotation behind those names is fine workmanship. Instead, may I suggest you evaluate some of Payless Decor's custom fit products such as our wood blinds and bamboo shades. They will fit your window precisely, and you won't have to flag down someone in the Lowe's aisle (good luck!).
