Its reverse applique (or Mole) by a lady called Abbie (anne) Searle.
She lives in Wadebridge and teaches all over the south west.
I tried a class with her at Exeter, but really only cos it got me on a machine for a couple of hours.
I didn't much like the result...too bitty/scrappy... it takes great skill to cut away the layers neatly and the class at Exeter was woefully lacking on lighting!
.....and you girls know me and my love of scrappiness!!! hahahahaa
When I first started quilting, I bought her book and that pattern....
which I read once, but never used as I just couldn't hack the scrappiness.
I sold both pattern and book to some girl from TSF last year, I wonder if she came over to TSP ???
Sorry if its you, but I can't remember her name!
