I just completed the Bronson Spot lesson in Season 5, Laces and loved it. So much so that I am warping up the Abalone & Ebony towel and scarf project. The draft for this includes floating selvedges. Is that a designer's choice for neater selvedges? The Bronson Spot lesson doesn't include floating selvedges, and looking through the Abalone and Ebony pattern, they don't seem necessary.
