You will need:
Around 250g (650m more or less) worsted weight yarn. Gauge doesn’t really matter here, as you are going to be going by length rather than stitch numbers.
I used Lion Brand “Shawl in a Cake” in colourway “Calming Desert” for the colour-changing part, and Malabrigo Worsted in “Purple Mystery” for the added strip, and an orange colour that I had left over for the picot bind-off. (I have since discovered that Shawl in a Cake has been discontinued, though you can still pick one up here and there). For the main part of your shawl, you will need about 150g / 440m colour changing worsted weight yarn. You will
need another 100g / 200m approx. of a complimentary colour or two for the end stripe.
4mm circular needle, as long as possible.
Tapestry needle for sewing in ends
