Hi David,
I think it is a very useful skill to have. If you have the time and the interest, go for it. My nearest neighbour (2kms down the track) has been making basket work for quite a few years. He does manage to make a living out of it by going to markets and organic fairs. He now also teaches one evening a week at a
local school and in the summer, teaches mentally challenged children - for free. He grows his own willow and often barters in exchange for what he needs. We got a couple of lovely baskets as a
gift after helping him with his roof - unexpected, but very nice. It is a beautiful skill and if my old arthritic hands would permit it, I'd love to do it. I just content myself with watching him, it's fascinating!
