I love how these came out, and will definitely be doing more! Lynda did a great job of writing a tutorial, so I'll let you visit her blog for more details. Meanwhile, I'm working on a tank top order for one of my regular customers, and sent her a picture of the top batik, and now I'm going to use the same technique - soy wax batik - for one of her tanks, only the dark color will probably be a vivid lapis or purple instead of black.
BTW, for those of you who live in the vicinity of Flagstaff, I will be at the Spring Artists' Marketplace at the Elk's Club on north San Francisco this Saturday, May 4th, from 10am - 4pm. I'll have lots of tie-dye, my new tie-dye necklaces and scarves, and some of my wall art as well... hope you can stop by!
