Thanks for the input guys!

I've just realised that I made a mistake! I wrote down the two people I thought were due yesterday in the wrong place! They're booked on the next one. (Stupid woman!!) So I have 3 coming next time.

For a number of reasons I think it would be better to hold them at home in the future if I can. The only problem is any health and safety rules and regulations I might have to comply with. I could only have three or four people at a time rather than the 10 I was hoping for, but I wouldn't have the outlay on hire of the room. I will re-think after yesterday, but I don't think I'll give up.

Janie, we had a sort of introductory discussion first, establishing how much they knew about herbs to start with and a sort of general talk about herbs. We were supposed to go for a walk in the fields around, but having walked it a couple of days before, it's been so intensively farmed for so long, there's hardly anything growing wild, so I put them in the car and took them home and we walked around my garden.
