A picture's worth a thousand words.....

(Click on photo for bigger image) A few plastic washers, cut up cardboard circles in two sizes and a pen with disappearing ink. Draw round the circles with the pen. Choose segments from the cardboard circles and draw around them. Outline in stem stitch ready to fill in with TAST stitches. Simple. No compass or measuring required! I could have used a compass and ruler and measured carefully but then I don't think I would enjoy it so much. There will be gaps between the circle motifs to be filled in somehow. And some of the TAST stitches may not be suitable, but that is part of the challenge; to use, not to use or how to use.
