Hi all, Ivwas coloring in this Popsicle today wet on dry and had some problems blending edges, particularly the red. The blue edges were much easier to blend on the bottom than the red up top. Is this issue related to the paint I'm using? Or just my technique...Why may edges become hard to blend?

I am using pyrrol scarlet Daniel Smith

And pthalo blue Daniel Smith

Thanks :) you guys are always so helpful!
