Mary Kr Thanks.Mary you can make any pattern with this stitch even you can make leaves too. I already upload one video making stem with bullion knot. I have a plan in the future to upload more videos in bullion knot.
Actually, this is dmc but in a ball shape, one kind of thread has 6 strands and another kind comes in a ball shape in a thick single strand. You can use crochet thread even wool too. Thanks
