I didn't made it on size 3 needles. I doublt the yarn and made it on size 13 needles. I post the picture below for you to see.
Yes, I did wear it with proud since it was my first sweater
But I have to admit that would I do this sweater again I would use different yarn. Mine wasn't really mohair, just mohair-like...pretty cheap though.
P.S.: As you can see I didn't knew how to decrease properly then
