To answer the closure question: I borrowed the idea I saw from a YouTuber named Megan Morris (her name on BB is @Margaron). She did a video on it called the buckle closure. The basis is a loop at the beginning, then at the end another loop big enough to fit the knot of your bracelet string (I double knotted mine) and then a bunch of square knots until the bracelet it long enough that you can feed the knot through your starter loop and then backtrack through the end loop - securing it. I hope that makes sense, but her video will show it much better 😁
