Balsa wood (Brooklyn)

Hi I know I put a lot of things on air right now about things I'm looking for any boss of wood pieces you might need or you don't have or you do have and you don't need because I'm looking for adjustable wood it can be flat it could be square it could be jointed it could be anything boss of wood if you could put it in a shoe box and fill it up that would be great and if you could thank you so much and then I could start doing my projects on my church
