Reddit mentions of Origami for the Connoisseur

My favorite origami books are:

Origami for the Connoisseur https://www.amazon.com/dp/4817090022/ref=cm_sw_r_cp_apa_X5GGzb0NC14YA

and

Genuine Origami: 43 Mathematically-Based Models, From Simple to Complex https://www.amazon.com/dp/4889962514/ref=cm_sw_r_cp_apa_L7GGzb1H9N4SY

Both books are well written and cover a wide range of designs (both in content and in skill level). The harder models in genuine will take hours to fold.

I have designed some of my own! To give a sampling, in increasing order of complexity (with diagrams!),

• here's a truncated tetrahedron,
  
• here's a double equilateral unit which can make things like an octahedron, icosahedron, "spiky ball," and many other deltahedra,
  
• here's a rhombic dodecahedron, and
  
• here's a compound of the cube and octahedron.
  
  My favorite origami book is John Montroll's Animal Origami for the Enthusiast, which starts out with simple, charming models and builds up to complex masterpieces like this lobster. It's one you can go back to for years. (I still have my childhood copy, inscribed "Merry Christmas 1988, Love Mom and Dad.")
  
  Another lovely volume, though not an ideal first book, is one called Origami for the Connoisseur. One of its highlights is an exquisitely beautiful seashell model. Here's someone folding it on YouTube.
  
  If you're curious about modular origami, Tomoko Fuse is a master of the field. This book ("Unit Origami: Multidimensional Transformations") is a hefty omnibus with plenty of lovely designs. Fuse tends toward a bit more surface elaboration and fussy preciseness than I go for these days, but her work is absolutely worth recreating with your own fingertips.
  
  Most of all, I'd encourage you to just try things out and have fun. There's action origami that does stuff (fancier versions of jumping frogs and fortunetellers), there's a big "tessellation" scene, where people fold intricate, two-dimensional patterns, there are flowers and franchises and figures. Any decent bookstore will have a papercraft section with an origami book or two. Libraries should have plenty of volumes available.
  
  Enjoy!
