After six months of virtual shop-keeping, one of my items made it to the front page treasury.
Of course I was only able to enjoy the glory second-hand.
I noticed several hundred hits on the Love that Aqua stack of three cups, and after consulting etsy support, found the treasury listing.
A nice surprise and confirmation that I should keep on keeping shop.
Look for it in the farthest bottom right quadrant.
I've learned that in feng shui, it occupies the "helpful persons" energy quadrant. Thank you Joe at etsysupport!
