Facebook, Instagram, Google Ads, Etsy, Amazon, "influencer" marketing, maker fairs, etc
Paid ads are tricky and labor-intensive to setup and to see actual results. Having a strong social media presence is always helpful, but again is a lot of work. After owning and consulting with several start-up retail businesses, I found that getting featured on Etsy, Amazon, a popular blog or social media account were the biggest game changers when trying to expand the brand, especially with a niche product like yours.
The one thing I'd add is (I hope you're open to some light criticism) - having professionally designed packaging, logo, and website would make a huge impact when it comes to POS, online sales, and getting people (influencers) to advocate for your brand. Other than that I think you've got it covered.
Anywho, this is what I do for a living so I might have to start charging if I write any more lol If you decide you'd like some help feel free to reach out!
