I used 2 layers of batting and some backing fabric left over from my last quilt.
I also used some polyester thread, its a 40 or 50 weight fine and shiny. The effect with the drawn lines is god for the spirals, of couse if this was not a sample I would have made them with brush off chalk.
The second piece is better to see, only one layer of batting.
|a better piece for viewing, the thread is black on a light brown fabric,|
More when I return from my holiday!
