Geri, PaperPieces.com has the Millifiore Quilts book by Willyne Hammerstein. La Passacaglia is the name of the most popular quilt in that book. This quilt is based on pentagons, not hexagons. It looks really hard, but it isn't The hard part is deciding which fabric & what to fussy cut!!! I am making Katja Marek's Mille-fiore quilt, but reduced the hexies to 1.5" as 3" are just too big.
I have been busy making Dear Prudence with 5/16" hexies. I've got about 6745 hexies in it so far & will have over 27,000 when finished. Here is a pic of it.
