​I've had 6 skeins of of Aran tweed from Briar Rose for a few months. I had a vision of this ruana in my head, really happy how it turned out. 

It's made from two rectangular panels sewed together. 

Cast on as many stitches as you need to reach the desired length. Mine is 116 stitches. 

First row. Half double crochet (hdc) 3. *Bobble stitch hdc 10* until end of row hdc to finish. 

Odd rows hdc to one stitch past the bobble, bobble - repeat

Even rows hdc to one stitch before the bobble, bobble - repeat 

The bobble should cascade 

Make it as wide as you want for one side. Make second panel. Sew together half way. 

You could make this all one color. Alternate colors. Make stripes. Mine has two longer stripes then two shorter stripes. This would work with any weight yarn.
