I used to make yarn dolls when I was a little girl. Didn't dress them, but they were still cute!
For the Mandala flower, here is a step-by-step photo gallery. To do this you start at step 1 with 7 strings attached and 6 with Einhängeschlingen on 7 folded thread. Other threads are then inserted by most of us with an ordinary shoelace knot. Overall, you need 98 double threads for the flower in the tutorial! However, it is important that there are 7 at the beginning and at least 4 are inserted at every step.
