I assume you are looking for a local live one rather than a virtual one.
Here in the states, we have extension offices connected with Universities. These extension offices have homemaker groups. The homemaker groups frequently have quilt guilds. My homemaker dues are $7.50 per year and my quilt guild dues are $12.00 a year. We meet at least one day a month 9:00 a.m. to 4:00 p.m. and we have at least one, but sometimes two UFO days a month for the same amount of time. There is also a night guild, but they do not set up their machines and actually sew.
It amounts to $1.00 per month for the use the extension office, which also has many tools for our use (rotary cutters, mats, templates, irons and boards), but I seriously look forward to loading my equipment on those scheduled days and moving into the extension office.
That guild and this group and I am in quilting heaven. You might have a similar resource in the UK -- just a thought.
Again, welcome, you will love it here. There is so much knowledge and assistance on these pages. Good luck with your search.
