Some acrylic/nylon yarn that reminded me of grass seemed perfect for another string bag and I am using the same technique and stitch as here.
It is not yet complete but the day and the setting were so pleasant that I recorded it on the bench outside the library.
It's going to make about a 16 inch square which should be the right size to duplicate the white one which inspired this whole adventure and is mentioned in the initial post. It doesn't really look as if it is going to be big enough as I am knitting so that is why I spread it out for consideration. Hmmmm. Will have to wait until it is finished.
