If I could have just one yarn, it would be Finull. It is a pleasure to knit with, stands up to years of wear, it's affordable and comes in a wide range of colors. I knit a lot of toys for grandchildren and use so-so yarn. Now i am trying to knit it away so I can use a good yarn. Why am I saving it just for me? It makes great Norwegian mitts, hats, sweaters, and now toys! I should have as much fun knitting the toys as the grandchildren have playing with them!
