I agree with you about mulberry not being really common [like oak or maple] but there are some around as you say. I hope I can get some more. I was just out in the shop doing some mandatory clean up [don't want the shop police citing me ] and I found one more piece of this........I think the other half of the piece I sent to DD last year........it was underneath the shelf on my lathe........looks to be in good shape for perhaps a hollow form!
Thanks Fred! Perhaps you will run across a piece or two before long...........one can hope!
