If at first you don't succeed

I'm nearly done with the Super-Natural Stripes cardigan. I finished the main body and sleeves, and was actually working the button band, when...uh-oh, I don't have enough of the main colour yarn! Oops! I thought, "Well, I COULD do it in a contrasting colour, but then it would look weird with the bottom of the cardigan in the main colour." I didn't want to do a half-assed job on this. I decided to frog what I'd done of the button band, and then frog the hem of the cardigan. This was the first time I've frogged something after binding off. I'm reworking the hem in a contrasting colour and will do the same colour for the button band. Then I need to decide if I want to do the same thing for the cuffs, or leave them in the main colour. I'll see how it looks when I'm done.
