Shakerag Top 2023

Has anyone tried knitting the Shakerag top-down instead of bottom up? (I just prefer knitting that way.) If so, would you be willing to share how you started out (until it joins at the underarm)? I am terrible at figuring this out and, at my age, unlikely to get any better at it! This is the 3rd summer I’ve wanted to make a Shakerag Top and this year I’m determined to succeed. Thanks!
