You guys are making me blush with all the compliments, thank you! I'm really happy with the scent and color combo but probably won't be able to re-create the design again. I'll just call it a free-style swirl because I couldn't decide until the very last minute if it would be ITP, drop or hanger style.
rparrny - I guess the technique was a combination drop & hanger swirl. I poured the base color, dropped a layer of each color on top then repeated the sequence. Then I used a gear tie and churned it around a bit . . . please don't ask for specifics because I wasn't trying for butterflies or anything like that. After the gear tie, I poured any remaining white batter over the top and drizzled with the leftover green/blue batter then swirled with a bamboo skewer.
