It is probably advisable that you are familiar with conventional corner to corner crochet before attempting this pattern.
This lovely textured shawl is made by using the corner to corner crochet technique combined with chunky puff stitches and the top edge is starightened off. The border uses front and back post stitches to create a rib effect.
The grey and teal shawl is made with a Hobbii Twister and the brown and cream shawl is made using a Scheepjes Whirl.
I made my one of my shawls from one Hobbii Twister but two of my testers ran out on the border so I would advise having a Twister Solid to hand just in case.
It could be made with any yarn using an appropriate size hook.
