OK, I found it. It's near the bottom of this older post in Bill Waldrop's blog, "Bill's Daylily Corner."

This is a really interesting blog with all sorts of information, so you might want to peruse more of it and I'm sure he'll have other information about conversions in it. That yellow tet conversion of SUNGLASSES NEEDED in his May 23 blog is fantastic!
Hope this helps.
