HI FiddlMouse,
I have encountered your situation where a combination of ornaments make a larger big ornament. It is hard to implement if you think of them as two ornaments.
To get my fingers and head around it I have practiced each one very slowly along with the other one so they can be eventually combined to make that really cool unique sound in one unified sounding lick. Good luck and I’m thrilled to hear you’re advancing to adding those licks to your tunes. Its the coloring of the notes in ornaments, bowing and timing that will get you that individual sound that is only truly yours. Fiddle on. R
