Yesterday, the latest round of When Colours Collide ended, with the prompt red and purple.
I started with one coat of MoYou London Purple House and sponged a gradient with Purple House and aEngland Percival. For the stamping I used the same polishes (just the other way round) and MoYou London Porcelain Collection plate 02. I fixed the stamping with one coat of Bundle Monster Smudge Free Top Coat and mattefied it with one coat of Picture Polish G'Day Matte.
aEngland polishes are available at various places, you'll find a complete list of retailers here.
