I have recently enjoyed the Online Card Class Watercolour for Card Makers. It came at a time when I couldn't do much crafting due to lots of work plus 7 stitches in my crafting arm. However I did manage to produce some cards and I love all the things that I have learned - and have loads left to try as well.
Firstly some watercolour backgrounds
then some watercolouring stamped images - my card is a total copy of the one in the class (not as good obvs) as I have the same stamp set - yes - by Clearly Besotted! (sentiment is by Avery Elle)
