While this isn’t an exact negative of yesterday’s Project Pack exercise, it’s almost there.
In this case, the tile is a standard, 3-1/2" square and the basic tangle, Huggins, isn’t the crazy version. I also changed up the highlight area in the center of each Huggins element a bit.
I’m finding that doing the black tiles is actually also improving my regular shading. Either that, or the agility of my brain is getting better at switching between the two types.
