As a general rule, I charge anywhere from 5 cents to 25 cents a yard. I'll charge more or less depending on how fine the fiber is. Or if I hand dyed the fiber myself, or prepared it from raw fleece. I'll also consider what I spent on the fiber itself. If I get a good deal, I'm fine with passing that on to the buyer. Besides, I sell my hand spuns just so I can buy more fiber!
Gorgeous hand spuns by the way!
