Here is the repeat of the pattern highlighted by red lines.
Frame starts at row 69 stitch 37 for all 3 sizes.
The body starts at row 89 stitch 49 for all 3 sizes
Do you see the count here? pattern adds every 10-th odd row.
Stole and small katetka shawl have 9 repeat's of the diamonds horizontally
Large shawl has ... (have you guessed? you have guessed tight , it's a double :) - 18 repeats.
So here we go :)
Squares are 9x9 and 18x18 repeats acordingly
Now the stole... as 9 horizontal and 33 vertical repeats. Can you make it shorter? If you look at the holes based charts, the repeat equls to 1 wie border diamond or 3 teeth. So make it as large as you like :)
