This is a pretty hand knitted jumper in the Kaffe Fassett design of Persian Poppies. It feels like a variety of yarns has been used - there is some that feels slightly hairy, like mohair and there is also some sparkle in there. It may be a cotton/acrylic/wool blend.
It's in very good hand knitted and used condition and there are measurements in the photos. Really lovely and great textures.
Please check the measurements to be sure of the fit.
