Is Steve Lindsay's normal leafy style defined as 'blackleaf'?
Is there really any book out there that is a step by step this is how you draw it... or basically just lots of great examples of good blackleaf in print?
Steve Lindsay's is a style in itself or at least I have identified it as such in my glossary. That said, just about any style of ornament is a variation of one of the basic styles.
The only step by step I know of is the Ron Smith advanced book.
