It has a lot of good reviews.
I would be somewhat interested in designing my own garments because often I am dissatisfied with what is out there. I find it difficult to find stylish, young, and sophisticated garments. That being said I have a long queue on Ravelry and I have found more and more of this type of sweater etc. Especially since more people have discovered knitting.
It would be helpful to know how to create a garment for alteration purposes though. For those times you love a sweater but want a different type of sleeve or neckline or whatever.
