Your best best is to join a weekly group, or form a new one, is via a guild.
You can check the details below out at Quilters Choice quilt shop in Jupiter
661 Maplewood Dr, Jupiter, FL 33458 (off Indiantown Road east of 95)
(561) 747-0525
They would have current information than my feeble memory.
I don't remember there being a Jupiter specific guild - I think you're between the PBC and PSL guilds, with Jupiter/PBG quilters going to one or both.

This guild was formed from former members of the PBC guild a few years ago.
They meet further down in Lake Worth, but I think some of their members live in PBG.

http://www.pslcrazyquilters.com/Looks like their Nov meeting was today, but there is a sew-in after Thanksgiving.
That would be a good opportunity to pop in and see what's what.
Good luck.

Here's another PSL quilt that popped up in a search
Never heard of them (but that doesn't mean anything)
