Hello and welcome Grannygrotbags! (My kids used to enjoy that programme 😀 )
Morsbags has been going since 2007 so some pods will have come and gone, so I think your plan is a good one. If you don’t hear back from the pod you messaged, feel free to go ahead and start your own pod.
If you’re a sociable sort, then sewing with friends can be a lot of fun. You could mention morsbags to people you already know and see if any of them would like to join you. (This is how I heard about morsbags, back in 2007.) Other ways of finding morsbagging friends include putting posters locally in shop windows / noticeboards, articles in local papers or on local radio.
Good luck Grannygrotbags, let us know how you get on.
