I have added Butternut to my wood types for most bases.  You will find Butternut is a light weight wood and the grain pattern is comparable to Walnut.  Butternut is a softer hardwood and would be comparable in softness to pine and its weight.  Give it a try, I believe you will like Butternut.  I have a limited supply on hand.

I have found some spalted maple logs and have begun sawing them into usable lumber.  The spalted maple will be available starting in the fall of 2022 on a limited basis.  Stay tuned.  Image of spalted maple with dark line characteristics. 

I have added USPS shipping on orders that weigh less than 10 pounds.  If you have a small order, USPS may save you on shipping costs.  When you are processing your order, you will have the chance to compare the cost differences between UPS and USPS.
