Great advice Pattern Pile!
I'd say creating and posting your actual made items (from your patterns)
in your social channels,
And the biggest for me at least, has been maintaining my own website
where I sell my PDF's from.
I see it as a hub where all my marketing efforts point back to.
Good luck going forward,
I'm so happy to see this wonderful medium change the lives of so many of us!
Hurray for PDF's!
Many Happy Hugs & Smiles Everyone!
