This pattern includes written instructions and a hand drawn chart.
The peach version in the picture is made with a Whirl and the rainbow version with 1300 yards of Dreamers yarn.
You can use any fingering weight yarn, I would advise you to use no less than 1000m. But you can also use much more to make it wider. If you want to make it longer, I would advise you to add multiples of 20 stitches to accomodate the lacy pattern (which is a multiple of 10) and add 1sc on each side of the border pattern each time you add 20 (the border pattern is a multiple of 9). I can help you with the math if necessary.
Of course you can also use thicker yarn with a bigger hook. There are notes in the pattern about weighing your yarn to ensure you make the most of it.
I have included 2 options, a simple one with 2 borders and another one with a repeat of the border in the middle of the shawl.

Have fun!
