I do that sort of thing in a local cafe. You might be better having it in school holidays than monthly, especially with school aged children, they tend to have weekly or term-time commitments which might clash. Manchester art gallery have a monthly family art club on a Saturday afternoon, you could check out the art gallery website for more details about what they do.
Thanks for the tips will have a look. I work lots of hours so can't really do something in the holidays would need to be the weekend. I think I am going to trial it and see if there is the interest.
InMySpareTime can I be cheeky and ask how much you charge? Most people want to pay £6 for 1.5 hours but I don't think that would cover materials and room hire. Am looking at some cafes too.
Also going to offer a free session to people who are happy to share their skills. I have a crafty brother happy to help and my mum is good at helping too. I am more an organiser and someone who knows their way around a sewing machine. I did use to help run playschemes so its not totally out of my comfort zone.
I charge £2 per puppet made, during a 30-minute session. People are very happy with this, to cover materials, and I have no room hire to pay, in fact I am paid £15 per session by the cafe owner as I bring in trade.
