I recently got some EWP from the Hardwood Store (20 bf 4/4, 10' x 8"). It was advertised as "white pine, knotty" so I wasn't suprised when it was delivered a few days ago. The knots are grouped in clusters and there's clear wood in between them (42-46" maximum). That'll probably work for a smaller project but there's still gonna be some waste in that 20 bf if I want to use only the clear wood. I allowed for about 20-30% waste and it was was only $1.35/bf so it's not painful to lose some.
Lowe's has clear white pine but I don't know if it's EWP.
