Step 11: practice practice
I have been spinning for almost four years now, and I'm still refining my technique. Don't expect your handspun to be perfect right away, or ever - that is part of the charm of handspun yarn. Experiment with spinning different fibers and thicknesses, and try out different styles of drafting.
Most importantly, make things with your handspun! In the words of my spinning teacher, Maggie Casey, a spinner who doesn't use their yarn is like a baker who doesn't taste their bread. Knitting, crocheting, or weaving with your handspun will give you valuable feedback, and help you make informed choices during the spinning process.
