I've never made one because I'm not a shawl guy, but provide the yarn and I'll make it. I've seen it look best with an ombre from a yarn cake.
Kind of got it down to a science. Provide the yarn and I'll make it. Top color is usually one skein by itself.
Send me an email (scott@all-a-runde-world.com) if you're interested, and we can coordinate deliveries from there.
