Threadless and Etsy and Printful Oh My

I spent the day trying to find a platform to sell printables. In fact, I just want to sell Christmas coloring pages that I had created.
Inadvertently I discovered Printful.
It's a lucky strike really, they have products that my Threadless shop doesn't have and it would be nice to be able to offer Crypto-inspired underwear and hats. The problem is they don't host a shop so I now need to learn to set up my own shop. All the steps to likely having everything where it needs to be.
In the meantime, fun christmas coloring pages will be found on my old etsy account for cheap cheap by tomorrow if not tonight. lol
in the mean time check out these men's undies and tell me they are not the bomb with my "Send Nodes" design lol
