Well, I'm not the best person to be giving advice but if it were me, I'd just jump in and go for it. What the heck, if nothing else, it's practice. And that is what this is all about isn't it? Not like you only have one copy of the pattern. The stuff that I have done so far was way out of my league or comfort zone but I wanted to do it so I did. Sure, I know what the flaws are but most folks don't see them. And on the next one, I'll do better. And so on. Just do it!
