I have this class and the (physical) book.
The bit about mixing and painting the different shades of colours was literally like watching paint dry .. agonising! and I even tried doing it in the greens and just found myself wallowing in
green! ! ! (hahaha
)
BUT, listen to the class ... several times if you can ... and the theory is sound.
I particularly like the quilt she made with Diane Basch which they found glowing because of putting a pure colour next to a greyed out tone !!!
Still trying to replicate that one!
You get the ebook with the class so although it is a bit of a yawn, no piecing going on, it is a valuable class to have.
If you look through the class projects Pearl, you might find a quilt you recognize.
