Hi! I was born and raised in Lakeland, but now I live in Orlando.
Accordingly to Ravelry, there are two Lakeland-convenient knitting groups:
Larks (Lakeland ARea KnitterS) fiber artists meet at Black and Brew Coffee House and Bistro at 205 East Main St, Downtown Lakeland every Saturday 10:00A until Noon.
Four Purls - A place for Knitters and Crocheters from Winter Haven and surrounding areas who shop at Four Purls, Winter Haven, FL.
If you aren't a member of Ravelry, you should join and just search for these groups. It's as simple as clicking a button to join these groups.
