A very clever, easy and free design. It’s simply a rectangle that is folded! Genius!

One can adapt the pattern to any size and any yarn. If one uses needles resulting in a very firm guage, a liner may not be necessary.

Elected to use US 13, 9.0 mm needles for a somewhat tight gauge. CO 30.

Will include fabric lining, a couple inner pockets.
Used a drapery tie back with a tassel for the strap.

I couldn’t understand the third fold from the pattern photo sequence, but found the one posted left, which is clear.
