I chose the advanced samples because I felt I could follow along pretty easily. The only part I had trouble with was the threadbar chain. I found it really difficult without wax for the thread not to tangle. Other than that, I really liked learning how to hem things invisibly!
top to bottom: blanket stitch, running stitch, figure 8 knot (with no ending thread), overhand tailors knot, backstitch, basting, blindstitch, slipstitch, catchstitch, threadbar chain
