Crafting's Mystery-factor

Greetings!
Working on another new project this week. A knit tank top from Burda Style. The pattern is free!

I had been given some slubby silk/cotton blend yarn and this seemed like the perfect thing for it. I don't usually care for racer-back styles, so I planned to modify it. As it is turning out, I ended up with less of a 'Y' shape, but still it still goes in pretty far across the back. Not what I planned exactly, but since it will be worn layered anyway, I think it will still look great. Kind of hard to photograph, but here are some progress shots.

Loving the texture!

back finished!

This material is really stretchy. It looks ok on the mannequin, but she's not as big as me! I think it is going to be too short, so I am going to make the front and then see if I need to do something creative to add length to the hem on the whole thing. Just goes to prove that there's always a bit of mystery in any crafty project!
Have you ever made something you weren't sure about as you were doing it? Did it turn out ok... or did you end up modifying... or is it left unfinished? Would love to know.
Ciao for now, crafty people.
