Framing paper and canvas in same frame
I'm looking to frame a 19"x24" watercolor painting as well as a 24"x30" canvas painting (3/4" depth). I'd like to find a frame in the same natural (maple/beech) finish for both pieces to tie them together in my office. I'm finding lots of online stores that can frame one or the other, but I'm struggling to find somewhere that can frame both. For instance, it looks like Blick has a frame that would work for the canvas here, but they don't have the ability to do custom frame sizes and 19"x24" seems to only be standard for puzzles or posters(?) and will likely require a custom size frame. Ideally, I'd like to be under $200 all in, but I'm not sure if that is doable.
Does anyone have any website recommendations?
Is <$200 reasonable?
My canvas does not have painted sides. Should I avoid the "floater" style frames?
