What I have here is a rather unattractive Shetland wool sweater.
Its new purpose in life is yet to be determined, but I'm going to attempt to frog this thing. It looks as though it was mattress stitched together, which is great, because that means I will probably end up with 3 separate pieces of non-cut sweater. If the seems were serged, frogging would be pointless because each sweater piece would be cut and then sewn, yielding many tiny little bits.
Lets give this a go, shall we?
