Just a cool tip I use when I crochet bows; make a rectangle, take a strand of the same color yarn and tie a couple of times tightly (instead of wrapping) around the middle for a good pinch. Crochet middle and slip stitch middle piece closed. It creates a neater pinch and is also a good alternative to wrapping in the middle.
Beautiful embroidery. Love the way you show it and how easy it is to learn.
