I made these sweaters using the Bond Knitting Frame, the original frame. My son is such a big man, that it would take me forever to knit him a sweater by hand. He would check my progress each day when he got home from school. Some days he would tell me that it wasn't growing very much. I got so tired of him asking if the sweater was done yet, that I bought the Bond. . With the Bond, I could knit a sweater and within two days he would be wearing it.
