I have made a couple more Temari recently.
The first is in various shades of yellows and oranges. It is basically done by wrapping thread round the mari (the base ball) in a specific pattern using pins to keep them tight together at the circumference of the ball and then adding a band of copper coloured thread round the middle which takes the place of the pins to hold the threads in place.
The Second was done as a stitch along on the Talktermari Yahoo group which is a wonderful group to learn how to make these balls. The way the stitch along was done I didn't know what we were making when we started and it was quite an exercise in following purely written instructions. The result was a turtle ! I repeated the pattern but smaller on the other side. I am undecided if I should add anything more in the way of decoration to the termari or not.
