I have been using the above notch pattern for 2cm-wide 65-lb cardstock weaving elements cut on a Cricut Maker 3 (courtesy of the DC Public Libray's FabLab.) The 7.5° alternately plus or minus rotation of the crossed diagonals makes locked crossings that are 75°/105°. These can be used to corrugate crossings that are nominally 90°/90° (tabby weave) as deficit/excess, as well as crossings that are nominally 60°/120° (kagome weave) as excess/deficit.
