For my Halloween manicure I used crackle polish for the first time. OPI's black crackle over Sinful Colors "Summer Peach". The crackle is supposed to represent spider webs. I also did an accent nail of a spider, and I used the crackle as a French Tip. I made the spider with my dotting tools. My spider needs a little work. Not only did my top coat make the white polish for the eyes bleed a little bit, but I realized after I did it that a spider spins his web from his back end, not the front. Oh well! I'm still pretty happy with it.
