The plate I used is Konad Q1. I used OPI's 'Don't Pretzel My Buttons' as my base colour and stamped with OPI's 'You're A Pisa Work' and China Glaze's 'Custom Kicks'. Both of them worked just as well as the Konad polishes for stamping, so I'm very happy that I now have more colour options. To use both colours in the stamp at once I just put blobs of both colours on the plate (just make sure they don't leak into each other unless that's the look you're going for!).
