The mosaic technique used here is described in detail in the Mosaic Tutorial. Some of the stitches are not illustrated in the tutorial. I encourage you to explore with your sewing machine stitches.
The Suffolk puff flowers were made from circles of lightweight cotton fabric. Use a hand sewing needle to run a row of small stitches around the raw edge. Pull up tight, and fasten off. The diameter of the circle used for these flowers is 10 cms.
The approximate height of the embroidered dust jacket is 25 cms. The approximate width is 52.5 cms.
I used the pattern provided with Jane Grove's article "For my lady's closet". This article was published in an Australian magazine, "Innovative Machine Embroidery & Textile Art", Vol.18 No.5. It would not be a difficult task to draft your own pattern though.
