Lyda: "This is the first real embroidery stitch i learned, i used it on the seams of my apron dress." Vandyke stitch, several extant things have this on them in some form or another (see Medieval Clothing and Textiles vol VIII?
I love this crazy quilting seam. It may be one of my favourites. I began with a cretan base and laced that with the "party ribbon yarn. then added detached chain, straight stitches, flower sequins and beads.
