Seaglass workshop was fine apart from the old chestnut of participants disrespecting yours materials. I have no sympathy for myself because I know the solution. You give your students only what you want them to have. End of problem. However the heat must have affected me last night and I did leave large reels of wire lying on the table which were duly yomped into. I don't even mind that if people are making things but to cut it and twist it and discard it really annoys me. I handed a little rats nets back to one offender, smiling sweetly all the while and told her she would have to make something lovely with that before she left. She got the message and took it home with her which at least removed it from my line of vision.
This problem is of my own making. I'll have to cost everything probably and only gamble with what I can afford to loose. Isn't that the secret of the stock market after all?
