This is a generic knitting technique to knit flat and make a seemless pouch at the end. I’d call it Magic to have no sewing the sides , selvedges etc. The Pattern makes a Sample to fit an 8.5 * 5Inch frame of a book, tab, and can be easily Customized to make a smaller, bigger or deeper pouch.

The pattern comes with three options of
No Flap (Add a Zipper or Velcro)
Rectangular Flap
Triangular Flap.

Want to see the magic, Cast On!
