Here is an example of Moss Landing on a darker clay. The glaze is a darker earth-tone yellow/beige. After pouring on the Moss Landing, I dip the top in Breaking Blue glaze.
This pot will fit your 4" plant. I leave the inside of my pots unglazed because the roots like the texture of the raw clay. There is a drainage hole and saucer.
If you would like your items shipped, let me know and I'll look up the cost of shipping and add that to the listing.
I am a potter in San Jose. Please let me know if you have any questions!
