@jl Ik this is kinda late but the knots that go to the right are just forward knots and the knots that go left are backwards knots. Try watching Masha Knots video on alpha patterns.
I keep trying to do this pattern but with no luck 🙁 I tried to hover over the arrow & it doesn't show me anything. I'm so confused & there is no video or further instructions to help me. So bummed 🙁 .
