The name Cadie means rhythmic flow of sounds. This shrug pattern is exactly like a rhythmic repeat, hence the name seemed apt to me. This is a pattern for beginners, using only double crochets, single crochet and chain stitches. This shrug is made from a single rectangle, with no shaping. Minimal seaming is involved.
The pattern is written in US crochet terms in ENGLISH. This is a 13 page PDF pattern.. It has written instructions for the crochet pattern and detailed pattern row by row notes with pictures. There is a YouTube tutorial that explains in detail and I have linked it.
