@amyc3157 you need 10 strings for this, 2 on the left and 2 on the right for one color (the color of the two rows) and the rest for the color of the three rows. You make a knot with the two central strings, two forward knots with the 3rd string, two backward knots with the 8th string, and connect them into one knot, resulting in the little triangle of 6 knots. And from then you just take your outermost strings and start making the chevron pattern as usual.
This design is amazing for so many reasons (1) it’s SUPER easy (2) you can use almost any colors and it will work (3) you can get use as many colors as you really want (4) these are an absolute classic! (5) they teach forward and backwards stitch making them an amazing beginner bracelet. Those are my opinions but i think that this pattern is amazing and I definitely recommend 👍
