Karen B
Loved Kate Kos’s mini workshop and found it really helpful in my understanding of gouache as a new medium to me. Reasonably pleased with the outcome and now have more confidence to experiment on my own!

Kate Kos ta muchly for pushing me have a go at 'waves'! I am lucky enough to live by the sea and have painted the sea but somehow could not get to doing waves. You have kind of given me the path now and whilst I do not like my first effort, that doesn't matter because I am on that journey now and will do more.
