No matter which tangle you choose, there are usually many different ways to draw it.
Take Hollibaugh, for example. I’ve used curved, filled, flared, “holyhollibaugh”, coffered, wrapped, auraed, woven, swerved and mummy versions, to name a few.
So I thought it might be good to have a way to keep track of these versions all in one place. That way, I would have a reference of styles to choose from.
