I love these things! They make painting in a sketchbook on the go so much easier. They hold a fair amount of water, are small, durable and most importantly they don't leak so they are portable. I also like giving them to my children when they paint so we don't have to worry about mess too much. I do worry about my youngest turning every set of watercolors I give her purple but that is a different issue. Nothing will top a quality brush and a cup of clean water but having a waterbrush or two around has often meant the difference between me being able to get a sketch done or not.
Good news! I've started selling my mini Altoid watercolor paint kits on Etsy. For a limited time as a special bonus I am offering a free watercolor painted card with the first one purchased on Etsy. I have collected a lot of commercial tins during my watercolor painting adventures, but I always come back to this one for on the go come with me everywhere color.
Vegans look away! A few months ago I discovered the joy that is painting with a squirrel mop. They can be expensive but the Harmony brand is great and so affordable it doesn't need to last as long as Da Vinci or Isabey. What I dislike about squirrel is the fragility of the hairs and they lack of snap. On a whim I picked up a size six Silver Black Velvet brush not knowing what to expect from a squirrel synthetic combination. It got great reviews and was on sale at a great price. Love at first stroke. It keeps the best point of any brush I own, feels great in my hand and is more rugged than a pure squirrel hair brush. I now have added a size 10 round with a few more shapes heading my way. I can get a full set of brushes for the price of a single Kolinsky brush!
And they now make travel brushes! I'm in trouble!
