Knitted golf club covers

I'm now toying with the idea of designing knitted golf club covers for sale. I knitted one for a good friend last year and received quite a good response. A few friends have asked me if i can knit some golf club covers for them or not. I told them i can but they have to wait quite a long time. I dont have much time on hand to knit these days. Well, let's see how things go. Gotta put on my thinking cap.
