I have stopped buying precut blanks because of that reason,
I have found that "boring" wood cut on the bias or cross cut is more interesting.
Wood that has an interesting grain like botoce, zebra cocobolo etc is even more breathtaking.
If you were going to build a large piece of furniture, would you let the lumber yard match your panels, or would you match your own panels?
I look at pen blanks the same way.
I may not get as many blanks as a supplier , but the woods I turn have "interesting properties"
