Hi guys, I am practising the chevron and zig zag patterns with Gelish (At least trying to!) I have found the easier way seems to be cutting strips of scotch tape with pinking sheers, sticking it to the white colour and painting darker colour over the top. Trouble is whether I cure it after or not, every time I peel the tape off some of the darker colour has seeped into the white! Any advice or other tricks of the trade please?! Xx
