I have what a dear friend has termed "fat fingers". She didn't believe they existed till she saw mine. Yet I've perservered through learning to knit and am pretty decent. So don't give up on your ham-fingers. I'd start at a crafts store. Something like knitting can quickly lead to frustration. Having human guidance will cut down on initial frustration and make you less likely to give up. Who walks out halfway through a lesson? Even if you want to, you won't. So I vote for Michel's; it'll hopefully keep you knitting.
