I used the 80 peg 3/8” gauge loom to create this pattern. I also used about 1/2 a skein of Red Heart Boutique Unforgettable Stained Glass Yarn, but would suggest also you could use Lions Brand Landscape and yarns similar in this length of color change.
This is an exciting technique to make variegated yarn pop, and do an appearance that looks like entrelac but isn’t.
There is video tutorial for the stitch and the crown. Plus written instructions and some photo instruction.
