Scrumptious beyond description, this stuff is total addiction, as all Tosh lovers know. I haven't tried machine-washing, but my wet-blocked swatch dried to perfection with absolutely no change in size from its pre-dunk measurement.
I am a Madelintosh junkie and love this Pashmina yarn. It is very soft. The only reason I didn't give it 5 stars is really not JBW's fault. I purchased a hank of this colorway at a LYS thinking it would be enough to make something with. I found that I needed more yardage. I ordered the same colorway from JBW, but when it arrived, it doesn't go with the other one all that well. I will have to do some serious mixing to make it work. But, we are told hand dyed yarns are like this, so I can't blame it on anyone else but me. It is a lovely yarn.
I used this yarn to make a shawl for myself. The yarn is wonderfully soft and drapey. The only downside is the expense. I needed two skeins for the shawl and had trouble justifying the expense. I know you get what you pay for, so if I could have given a 4.75 for the yarn I would have.
