I just taught my first tatting class. I had a two hours to teach basics and hopefully a pattern. It was a simple chain and ring flower and a simple butterfly. Two hours later neither of my students could get past flipping the stitch.
I don't know how to teach the flip any easier. My sister, who only cross-stitches, was able to flip a stitch in a half an hour.
More research must be done. What is the easiest way to teach someone how to flip a stitch?
