Any artist out there? I did something, and I don't know how I did it.

I was painting colors side by side and tried to make each color its own rough, shabby chic band. I have one brown band next to a white band and I noticed that the brown band has a dark brown edge next to the white. It's still all rough because it's shabby chic, which means that the whole thing got dried brush with white, but for some reason, the edge of the brown band does have a darker brown line and I like the definition. I tried to repeat it but nothing comes close.

What did I do?

1. Pics would help, plus paint and other material info.

I love happy accidents!

2. What paint are you using?

It sounds to me like the solvent in one of the paint colors pushed brown pigment into a narrow pile along the edge of the brown.

3. acrylics.

I had a great conversation with GreenPartyVoter

I have homework to look up these terms:
Search for hard edges, halos, tide marks, blooms, blossoms plus furniture terms. Like painting, distressing, refinishing?

And this other possibility: "You might have just dragged the brush longer and ran out of paint until you only hit the highest edges."
