Starting a new hobby is one thing, but joining a club will help you meet new people in the process. Sites like Meetup can help you find a group of people with similar interests, and you can work on creating digital meetups with new friends in the process.
Creative clubs can also be a boon in helping you stick to mastering a new craft. A great example? Good Housekeeping's Stitch Club, which connects avid crafters and DIY newcomers together in a community to inspire.
