A personal word of warning. Molly's are a really cool design but like darksoul said they aren't super easy to execute. They small working limbs are under an incredible amount of stress and so they have a much smaller margin of error for an imperfect tiller. I have built about 10 successful long bows and flat bows to the intended length and weight, that still makes me a novice at this but I do have a little experience and guidance to draw on. The last bow I attempted was a mollegabet made from a beautiful osage orange stave which is some of the toughest, most forgiving wood out there. I carefully followed advice from both blackhawk and and others who were quite experienced with the design. I even backed it with some premium kangaroo rawhide. I had some splinter issues due to a tiller that wasn't quite perfect, I fixed the tiller and then after about 1000 shots it catastrophically failed on me. I think you'd be much more satisfied and have a much higher chance of success if you build a straight limbed, bend through the handle flat bow for your first attempt. You will learn a lot about design and tillering and you'll have a much better chance of making that molly work out for you a little bit down the road. That's my two-cents. We'll help you along no matter what you choose but I urge you to consider changing the design. Remember this wont be the last bow you build, they're like a bag of potato chips, you can't just have one.
