I've never used it myself (yet). It is listed among the arrow woods in Toxophilus but Ascham doesn't seem to like it. That is assuming that what we refer to as Alder is what Ascham refers to as Elder?
One of my pet projects is to work my through all of the woods that Ascham mentions. So far I've tried oak, ash, poplar & birch. I have some beech on the way and want to try hornbeam next.
