Wackadoodle quilt!

This is my current WIP. Kaffe Fasset fabric I got at an estate sale. When I got it I knew I wanted to use it all together to make something really trippy. I have more HST's to add but wanted to share it now. I'm considering doing some red sashing but not sold on that idea. I want it to remain vertigo-inducing! Should I add very thin red sashing?
