I'm not sure I'd trust instructions from someone who doesn't know the difference between a granny knot and a square knot.
I may not have communicated that clearly in my post- was trying to get across that you could use either type of knot. Re-reading it, I can see how it sounded unclear. I honestly don't know many knot names- it was my husband who made it & I was writing down what he told me.
Thanks for leaving a comment. I always like to know what you think of the projects I highlight!
