Hi All:
I think that Chuck H. is correct on this question! In the past,I too have had wood with a lot of tigre stripe turn out to be wavy. I learned that it was caused by NOT using sandpaper tht had a very hard backing when used.
The sandpaper must not be permitted to "drop" down into the softer wood and remove more of it than the wood that is harder! This takes a lot more time and skill than just sanding until the wood is smooth. While I like tigre striped wood, I find it to be more time consuming to finish!
Stay well,
Franchi
