I did it with the help of the Liquid Watercolor posts on the Taylored Expressions blog - starting here. Day 1 starts with Color Mixing and Painting. Then if you click to Day 2, it's Color Wash and Shimmer Liquid. Day 3 is Detail Painting. Day 4 is Smooshing and Day 5 is Painted Plaid.
I worked through all of those days and have a lot of cards for my personal stash, but not quite good enough to share here. However, you have to check out Day 4 Smooshing. First of all, it's the most beautiful card that I've ever seen. Secondly, Gayatri has done a fabulous video that walks you through each step and at the level that I need. For instance, you can see exactly how much liquid watercolor to put down to smoosh with, how different water misters acts, how to build up dimension (both in smooshing and then she adds detailed color later), how to splatter it and more.
I went through the video step by step, pausing it and replaying it repeatedly while I worked on my own card. Not in a million years do I have the skills set to replicate exactly what she did - but I'm happy with my card. And more importantly, I'd actually do it again!
