This is a knitting pattern written in Japanese but the basic construction is easily hacked. Knit your own rectangles or this could easily be adapted as a way to upcycle old sweaters--felt wool sweater(s) then cut and join rectangles as shown. Could use store bought bag handles or stitch handle from additional felted sweater fabric, maybe around upholstery cording.
NOT A FREE PATTERN, can still view for inspiration.Tunic pattern
