ETA: Done! Selling on other Platforms > MakerPlace by Michaels
We can do it here.
We can make a dedicated Michael’s MakerSpace (public) category here, like Selling on other Platforms > Etsy or Selling on other Platforms > Walmart.
Would that be helpful? Could you comfortably direct Makers here? 
If yes, and if it gets big, we can make a private group and category, like @Handmade and Amazon Handmade.
