This one was a bit too easy, really. However, I keep reminding myself that the whole thing will be quite ‘busy’ when the squares are joined together, so I think it’s probably OK to have a few very simple circles among the more complex ones.
This is a square of heavy cotton furnishing fabric that has yellow flowers printed on it. I deliberately cut the square so that the printed circle was not exactly central, and then centred an outline upon it in whipped running stitch. The circle outline is approximately 2.5″ in diameter.
