Leadlighting: if you haven’t heard of it, it’s a great technique to make beautiful multicolored nail designs with stamping as an alternative to the time-intensive stamping decal. As far as I know, the ladies at Messy Mansion were the first to do this (or name it leadlighting). You stamp over a light polish base, then use jelly polish to color in the negative space.
I actually only have one jelly polish, so I made my own! The lovely Jacqui at CraftyNail suggested this to me after I envied her leadlighting mani using OPI Sheer Tints. I basically mixed my existing creme polishes with a little bit of top coat to make the pastel jelly. I think I probably should’ve added more of the top coat since mine is still fairly opaque, but I think it came out alright!
