Going too fast.....I always say I'm too dumb to know I've taken on a project that's beyond me. The very first piece of furniture I refinished was a piano....the second an antique (rolltop) baking cupboard! Both turned out great but if I'd stop to think about either for more than half a second I wouldn't have done either one!
I think the secret to that kind of attitude is....you have to be too darn stubborn to admit defeat....that's definitely me, the more I can't do something the more determined I am to succeed. So.....my advice before your attempting this is.....make sure you are bullheaded and stubborn enough!
From what I've seen of your first project.....you'll do just fine.....and there are lots of very talented people here to help out with any questions you have.....not me though, that's for sure.....I don't have a clue about how to do what you're attempting but I'll say one thing, I'll sure be following your progress with great interest. You are going to share it as a work in progress, aren't you? Please!!

P.S. You two make a great looking couple!
