If I'm looking for something specific, a Google search such as "machine embroidery pumpkin freestanding lace" will yield many Etsy designs very inexpensively. They usually stitch out very nicely.

Kreativekiwi also has designs that turn out much larger than your actual hoop size, by doing several hoopings and lining the previous one up to stitch to another one. Their videos showing how to do this are very helpful.
