I started with a four-by-four setting for the ‘Road to California’ block (AKA ‘Jacob’s Ladder’) and turned and twisted and recolored. The goal was to make the original block hard to spot. I think I did that.
I then went back and eliminated the extra seam lines on the corner and side blocks to make them easier to piece.
The border is ‘Flying Geese I’ from EQ’s ‘Set Auto Borders’ feature.
