I have done zero decorative stitches so far with my new-to-me sewing machine. I haven't even made a button hole in about 20 years...
I do have some ideas to try my fancy stitches on a string quilt/crazy quilt hybrid.
I'm going to make some "Bad Sunbonnet Sue" blocks, one of which will be prison Sue and her number of 8675309 will be on her outfit. If that seems familiar it is Jenny by Tommy Tutone.

So far that's all I have! But I see many wonderful things by creative people. One of the ladies in my Tuesday group uses a preset curving line for most of her preemie quilts.
