Crackle is quite amazing because it allows for very twilly graphics but it can also produce incredibly blocky designs. Our show and tell has some stunning examples of the diversity that can be found in this structure, from drapey scarves woven in silk to good solid placemats and absorbent towels woven in cotton, and some luscious blankets woven in Harrisville Shetland and Jagger Merino. I think you'll be blown away. Like Overshot it is a twill derivative and like Overshot its design potential is amazing.
