@BeautifulB Hi! 🙂 I do have some tips, first of all what I've learned from alphas is that they look really good when you keep your knots genuinely loose and not too tight (The pattern looks a lot more clear and readable this way) and to keep all of your knots at the same tension, which means don't have some knots tight and some knots loose, keep all of them the same way.
Also at the ends of your alphas instead of doing a forward knots or a backward knot you replace it with a forward-backward knot or a backward-forward knot and it keeps the bracelet in a straight form. This is called the "Straight Edge" technique and MashaKnots has a great tutorial about it on YouTube and is very informative about it.
I hope that helps a lot! 😉 Let me know if you need to explain anything else. Good Luck!
