I have learned about so many via a Facebook puzzling forum I joined. There are lots I enjoy, but a few of them are: Pomegranate (located here in my home town), New York Puzzle Company, eeBoo, Dowdle, Cloudberries, Laurence King, Modern Puzzles, just to name a few. This SXM puzzle came in only 500 pieces, but I prefer 1,000 pieces.
