I have 20 10 Spalted Sycamore blanks (4x4x1 at a minimum, most slightly bigger). It has awesome spalt and is pretty solid. Some might have some minor checking that can easly be stabilized with CA glue. I have made a few call from it and finished with CA. While I am still experimenting and fine tuning my calls sound pretty good and I actually killed two (2) nice birds this year after calling them in with two (2) of my calls. 2 blanks will fit in a small flat rate box. I'm trying to get some more start up money to buy some more slate, glass and alumimum. Would like $4.00 a blank.
