Fun fur scarves are "all the rave" over here at the moment. Personally, I hate working with the stuff!! It's not easy to work with and even a person with perfect vision would find it hard to see their stitches.
If you have the patience and the tolerance then by all means. But if you're anything like me (ie easily frustrated by uncooperative darned yarn) then I wouldn't try it. LOL
Seriously, though... I do happen to like the look of it. I even have one of the fun fur scarves (made for me by a friend). But be warned it takes a lot of patience (and maybe a magnifying lens).
