This is a pattern for a PDF download with a chart of table to show colour placement. The free version is on my blog without the table and chart and can be found here

A lightweight drapey shawl of granny clusters.
Colourful stripes are easy and relaxing

You will need a 4mm hook, approx 150g of 4ply wool for the main colour and approx 20g each of 6 contrasting shades.

Wingspan is 185.5cm / 73 inches with a depth of 85cm / 33.5 inches.

Notes
The pattern is written in UK terms. The main stitch is a UK treble, which is a US double crochet.
Contrast colours (CCs) are used three times each with 18 stripes of colour in total.
In established pattern, the CCs are placed every fourth row.
Rather than sewing in ends, I attached tassels to hide colour changes. Knot ends together first before attaching tassels.
