I was right!
Using the same loom, It makes a thicker, more cylindrical cord with a shallower helix.
Step 1: Starting.
I cut two equal strands of each, then folded them in half and knotted at the fold, making sixteen individual strands.
Threading the strands through the loom, I arranged them in opposing pairs - two white strands opposite two white, two purple opposite two purple etc.
- I only used this arrangement to make the steps of the weave clear, but the result looked rather good.
