"Oh, I'm pretty sure I could be worse than everyone you've taught. I'm hopeless at that kind of thing. I'd make an awful housewife. I can't even sew on a button. I mean, I try, and it's passable, but I'll never be good at it. I'd like to learn from you, though. Yeah, next time, you can show me how."

And it makes him wonder what he could possibly teach Ned in return, because as far as he's concerned, Ned knows far more useful things than him. Advertising isn't a talent one can teach, and not necessarily something Ned would want to learn, anyway. And beyond that, he doesn't have talents, at least, not as far as he can tell.

"I'd offer to teach you something, too, but what could you possibly want to learn from me? I'm learning everything from you, not the other way around. I mean, I'm not complaining about that. I like what I've learned from you."

And yes, he means that in every way possible, including the suggestive ones, which is obvious from the pink tinge to his cheek as he says it, because his mind has gone to a decidedly inappropriate place.
