I was very pleased with the result, and even more pleased when it was described by one of my friends as "very Laura McCabe"!
I have written this up as a tutorial, which is available from my Etsy store.
Earlier in the year, I blogged about going on Laura McCabe's beaded sculpture masterclass, which I attended the week after I got back from my holiday. I was very proud to take these little spiky balls with me to the class, and Laura liked them too! I'll blog about the masterclass itself another time.
