Yeah i have actually put off mine for meh 2 n half years. I got so busy with everything else and the worst part is my design changed a little bit as to what i want it to look like BUT luckily i haven't painted the tail yet its still pinned an folded on a shelf.
I keep asking my mom for help on it but she refuses to touch it out of fear it will get messed up an i keep reminding her its my first time making my own tail if mistakes happen they happen its no big deal we can always make another. But yeah its a LONG work in progress.
I think i also put mine off because i gained a bit of weight since i last cut out the pattern so im afraid i will have to loose some belly fat to fit into it but its no biggie.
Im glad you're doing good.
and i can't wait to see new pictures of your turquoise tail.
