Sweet little bow-nice profile and tiller, great job on that one. I really like the effect of that orange dye with the black skin, too. That stingray grip is cool. The smile on your daughter's face says that she likes it-looks like she's handling it well, and it has plenty of room for her to grow into over the years.
Black locust (we call it 'yaller locust around here
) is naturalized in many parts of Europe now just like a lot of Eurasian trees are naturalized here. I've seen bows on here from all over Europe made from local locust over the years. The early European settlers took it back home with them because the wood is so decay resistant. One of the few woods that can be in contact with wet soil for years and years without rotting. Also one of the absolute best firewoods.
