Hill-and-valley weaving with locked crossings

Corrugated surfaces can be woven using locked crossings if the crossings are locked at some angle other than 90 degrees. The sample above was woven using crossings locked at 100 degrees (80 degrees on the acute side), with the distance between crossings fixed at 3x the width. The resulting hill-and-valley corrugation adds a lot of stiffness to the woven panel. The 1-inch wide cardstock weavers were made by hand using a paper cutter and 0.25-inch diameter hand punch. Below is the pattern used to cut the weavers.
