Inexpensive solution; odd size
Two posters, each 26 x 13, require a very simple inexpensive black frame. I found two plastic frames in a different size with thin plexiglass in a big retail store, but now I want to roughly match. I have tried Dick Blick, Jerry's Artarama, Cheap Joe's, JoAnn Fabrics, STAPLES, Wayfair, and a bunch of framing sites. I don't want to spend more than about $25 US on each of the frames--truly, these require an inexpensive solution (okay, may I go to $35 each). I also considered a Neilsen kit, but the pricing gets high when I buy the two pairs plus the glass--this may be my only available solution, but I was hoping for more ideas and sources by posting the question here. (I usually post in pastels and watercolors.)
Thanks for the help!
