The butterfly Banner starts

I started the crochet, freeform as you see, involving various stitches and approaches, and here's the first few inches, with a butterfly tentatively trying it out!  

This will get to be more open as it goes, with darkening colors introduced.  If the light colors at the top become too evident, I'll paint them a bit. 

Right now I'm using my largest crochet hook which you can see down left there.  With the finer threads to come, it means the openwork will be much more airy and open.  But the top needs to be a bit sturdy, as here.
