Patrick Kelly, RIP,  used buttons on his designs.  I put buttons on a group hats several years ago.  This big beret have corkscrews like Patrick would distribute on his designs.  The yarn purchased from Artisanal Yarns, RIP, at Rhinebeck.  It's very drapable and big.  The yarn is Mauve and navy cotton wrap polyester and wool corkscrews.  Head sizes 21 to 22.
