For those who love hand made lace.
I took a few lessons from this and have some theories. First, picots will require more experience, and I'd like to find out if knotted picots are period. Second, it is possible the thread I am using is too thin and narrow for the pricking. Third, graph paper is your friend - that's how I figured out the crossing section. Fourth, while tension is important it is possible to tension too tightly - the wider trails are where I kept the tension very low.
