This is Jan Z. and her amazing quilt. It is beautifully appliqued and embroidered with so many little details! She says it is a Piecemakers pattern from 2003 that she has been working on for a long time.
She embroidered around each applique piece with black floss.
My goal in quilting was to stay out of the way of all her work while highlighting it with stitch in the ditch - a LOT of stitch in the ditch. I used Invisifil and Bottom Line thread for almost the whole thing. Invisifil is great for stitching around applique; it is so extremely fine and comes in colors, unlike monofilament.
