For my recent manicure I brought back the crackle trend to combine it with gel polish from Gelish. I used China Glaze Crackle Glaze in Cracked Medallion, thinking it would look nice with Gelish Gardenia My Heart. The final look is pretty cool, but I think a bigger difference in the base color and the crackle color would have been more eye-catching.
Either way this design is easy to do on a gel base. After applying and curing all my color layers and top coat, I buffed the nail I wanted to put the crackle polish on. Then I applied a traditional polish base coat. After it dried, I proceeded with the crackle polish as usual. After that had dried for a few minutes, I used a traditional polish top coat, but you could also use another layer of gel top coat.
