Esther Rodgers, a fabulous fibre artist and an exceptional teacher needs our help. Please go read her story and help her if you can.
I already had her class on Craftsy and her class on the same topic from Interweave. Both classes are excellent if you are interested in processing your own fibre for spinning or felting. The topic is the same, but there are enough differences to make it worth my money.
One section in her Interweave class completely blew my mind, I've yet to make that particular yarn, but one day I will. Her classes have helped me to be better at getting the results I want from the yarns I make, so I can (and have) recommended those based on experience. I chose to donate because that would help her directly and she needs our help right now.
