Dresden plates have different variations all featuring a blade design around a central point. It is usually finished with a central circular shape.
The block first appeared in the 1920s but publications did not use the name consistently. It was more familiar in the 1930s as the Dresden plate. Blades can be pointed or rounded, and generally resemble a flower.
The entire block is made using appliqué. For large sizes, a ruler template is available, however, dividing the number of blades you require into 360 degrees will give you the variant for the blade angle.
