Bruce Wedlock replies: Kiln dried American holly is the purest white wood you can find and has an almost invisible grain pattern. It is available as 4/4 and 8/4 lumber, turning blanks, pen blanks, thins and veneer formats, the latter used for inlay designs, banding construction and stringing in Federal period furniture. It is on the expensive side. Premium quality lumber runs around $50/bf, and seconds with occasional knots runs around $25/bf. Sixteenth veneer runs about $20/sf.
The best source I’ve found for holly lumber and veneers is Domex Hardwoods at www.domexhardwoods.com. The have a wide variety for your needs. I have found them very reliable.
