You can use 1/4 Dresden plates for fans. I've seen them arranged into the corner of blocks and a tassel hanging from the corner. You can do stripes across a quilt by turning 1/4 fan blocks in different directions. You can do 1/4 blocks in a corner block and add an applique handle for umbrella blocks. You can do full circle Dresden plates into sunflower place mats. Make up a few and just start playing with them on your design wall.
