Alvin and Bobby:
Both of you, a warm Welcome. I hope you come back often and enjoy your visits.
Alvin:
Sorry cannot help with a pattern. Were you looking for a wall placque with the letters cut out of the background?
Bobby:
There must be a real lumber yard near you. Just go and ask if you can special order Baltic Birch or Apple Ply from them. It took me three lumber yards to find a salesman willing to do special orders. IIRC, he pulled out 4 books from whole sellers and only two whole sellers carried BB plywood. (No one would sell me ApplyPly plywood from Oregon, furniture makers and cabinet shops only.)
The next time I went to a fourth lumber yard, and they would only sell to me if I went to the whole seller to pick up the order (otherwise there was a minimum purchase to cover trucking.) Let them know you might be able to pick up from the whole seller, if they are willing to let you. But then again, just how many miles are you willing to go?

The 5th lumber yard only charged me a few dollars per sheet over the previous place. I am still using the lumber from that trip.
