Ethnic, Jacobean, Pastel Roses and Delft.
These 4 sets I digitized do do appliqué, reversed appliqué (mola work) and quilting with.
Each set has a lovely step-by-step photo instruction pdf file to teach you how to use the designs and also how to do reversed appliqué. Each of these sets also have some outline designs, which you can use to quilt with on your embroidery machine. With Reversed Appliqué / Mola work you actually "paint" your own design with your chosen fabric and it creates an incredible amount of depth in your embroidery.
