Sunflower Button Revisited

This video is a remake - with a difference - of a tutorial I posted 3 years ago. I've had a few comments that some people could not see what I was doing, so here is an updated version with the petal process more closely filmed. 

However, this is a different button - the petals are created in the same way, but the base is different, so that those of you who have already made the previous button can try something new. 

As with the original, I have worked this sunflower in the Ukrainian colours.
