Used to joint run a popular one in Somerset, it was featured in one of the mags six months or so ago but I was pretty much written out of it due to slightly control freak nature of other lady- funny really, was in my house for long enough at my expense!!!
We didn't charge too much, £1.50 it was but that was aprtly because we got cheap rent. We did try to put it up to £2 to cover teas but they refused- not the most generous of people!.
Mainly we attracted pensioners, specifically pergamano mad pensioners. Don't know why that was. We di also have a newish member when I left, Sarah who runs the Cheddar Stamper internet site, and she was really helpful (recommend site).
We used to give people tea when they arrived and cheapo biscuits (finances that was). Then we'd do a show and tell on a specific theme, eg Males Birthday. Then we'd do a demo- we had somebody from the Quillers Guild one week, I did triple Embosing, that sort of thing. Because of finances, we made up little equipment bags of enough to make a card and sold them for a £1 - £2.50 depending on contents, it was up to them if they wanted to buy and join in, or just observe. A bag would typically contain a versamark ink pad, a foam stamp and a small amount of powder, or home made quilling apper (shredder, 20p tool and a blank.
The groups were popular. We did allow under fives because our venue suited it and we were in the day, that helped. Holidays, etc were unreliable and a couple of times we barely covered the rent though.
I think £3.50 an hour is about right TBH, it's what DS1 pays for his art class which appears to basically be card making.
I've been asked to set up anotherclub here. I ignored it at first but the request was repeated with an offer of help last week and now I'm umming and aahing about it. The only bad bit TBH was the constatnt noise- I'm very sensitive to noise- and you couldn't shut up the older ladies long enough to do anything some weeks. Grrr. Rude when you have a demo planned.
