How hard do you think it would be? (raglan sleeve cardigan)

[laprettygurl]

I want to make a sweater for my kidlet using yarn I reclaimed from another sweater. It's a thin/thick wool.

How hard do you think it would be to make it from this?

I realize I'd have to work on straights. I wanted to use a zipper, so maybe one or two extra stitches on the open sides of the work?

This sweater is also going to have a hood so how should I do the neck?

thanks sooo much.
