I would be interested if there were any such courses. DD and I have introduced DGD to sewing, which she loves, and she has been making clothes for her dolls and now herself since she was 6 (she is now 10). I enjoy sewing, but I am not very good and I would love to know of adult and child course in the school holidays.
In fact I am thinking of approaching a local craft school to see if they would be interested in running one. I will be interested to see what comes up on this thread.
