Welcome!


Hi, I’m Anna. I did my degree in Textile Design at the University of Huddersfield in Yorkshire, UK, and have expanded my work into Graphics and Surface Pattern and worked for a number of years doing freelance work using my various skills. 

I have taught art classes in the past but designing online classes has been a whole new area for me and something that has taken me by surprise as I have loved it. 

I hope the lessons I have been learning along the way can help you too.
