Thank you so much for this lovely class, Claire! The lessons were easy to follow, beginner-friendly, and I had so much fun creating my own signature brushes. 
I haven’t made the QR code brush yet since I don’t currently use social media or have a portfolio, but it’s definitely something I’d like to create in the future.

Here are my 3 signature brushes (as a cat mom, I had to add a cute cat to my signature). I've already started using these in the Sardine Tin class I'm currently working on.
