I adapted a method I learned with Bridget Bailey in my tutorial back in the summer that involved layers (silk and velvet) and floristry wire. I estimated that I needed 9-11 per headpiece plus extras for disasters so I was cutting and assembling the layers for quite some time.
If I thought THAT was fiddly, it was nothing on the assembling of the sprig, which turned out to be more of a branch. (Note to self: Less is more.) And then the binding of the wire… suffice to say, they didn’t get easier and I’m glad I only had to make three!
