I'll have to delete one of these or you might land up with replies in three places. I think this is the best place really, so I'll remove the one in activities.
I was a member of the IWCL and found they have some good groups/activities (although I'm not a knitter!), and the people I met through it were lovely. I've let my membership lapse now though as I have a young baby and it's just not possible to make it to most of the things that they organise, particularly as I live near the border with Italy rather than in Lugano itself.
This user would like to thank trailingfidanzata for this useful post:
No I haven't been to the knitting group, I had been umming and ahhing over whether to join the Women's group (you can't go to any of the sessions without becoming a member of the IWCL) and in the information they sent me most people appeared to be 20 years older than me and I was wondered (could be wrong) whether there was a religious slant to the group which I wouldn't care for. All in all I didn't feel it was for me on reflection, that's not to say it wouldn't be perfect for you!
