Thanks dxb, and thanks to all for your feedback(s).
Now I have too much to think about again. That's what I get...but, that’s “a good thing”.
I am trying to say that the frost will only be on the edges of the leaves.
As a former Boy Scout I learnt that fringe on leather jackets etc. are not usually stitched on, but are cut into the “boundary” of the garment.
I found this:

“Wyoming Trivia Question January 1998
…Fringe was known by the mountain man as ‘whangs.’
What purpose(s) did the fringe on the mountain man’s buckskin clothing serve?
Fringe or "whangs" served several purposes in addition to the most obvious one, ornamentation. Fringe helped drain water off of the garment during rainstorms.* Whangs were pulled off and used to mend moccasins and clothing, to tie bundles or as bindings. In times of starvation, whangs could be chewed in an attempt to temporarily relieve hunger pains…” It always goes back to favorite foods doesn’t it?
*as of troy has noted
I don’t know from whence whangs.
