I love doing these. So much so, I don't sell them anywhere.
Just do them for my own pleasure. The refining of the design,
high contrast, fairly thick material, playing with the colors etc.
I do the screen printing of the letters myself.
It's not that technical, super low tech, just use enamel,
nothing exotic for ink or machinery.
I bring them to my church and let them disseminate them.
They are in a position to use them effectively.
Hate to say, here it is, now you can't have it,
but these are not for sale. Really I tried selling them
practically at my cost, but no one wanted to buy them even
at that low price. It's cliché to say, but it's a labor of love.
