Measurements:
The shawl starts at the shortest side which is 87 cm/ 34 ¼ inches. The left or straight side of the longer sides is ca. 165 cm / 65 inches long. The right or decreasing and hence longer side of the triangular shawl is ca. 190 cm / 74 ¾ inches long. All without the tussel. I have created a youtube playlist with some tutorials for:
The wavy edge at the start
The I-Cord on the back or left side
And How to hide threads in the I-Cord. You can all find them here:

We begin the shawl at the wider side with a special wavy edge and some short rows. Then we continue with a lace pattern and decrease gradually and constantly to make the right side longer than the left.
We will “paint” on it with different varying color stripes. The lace pattern repeat consists of x stitches and x rows. After finishing a pattern repeat in height you should have 1 repeat less on your needle. The last 2 repeats are decreasing faster to form the pointy corner. The color stripes differ from pattern repeat to pattern repeat.
The sides are worked with I-Cords. In these I-Cords you can hide your different color threads going along and hence you do not have to cut them and thread them afterwards. There are exemplanatory videos on Instagram or youtube to explain this and other stuff. Please find the links in the description where necessary. We finish the final pointy edge with a tussel.
