The sketch pad is from The Works at Ramsgate Garden Centre, it is just a little bit smaller than A4 has an elastic band to stop the pages blowing about and the paper is just thick enough to watercolour without going all crinkly and spoiling the pictures. I think they are either 2 or 3.99.
The brushes Winsor and Newton reversible ones (the brush bit goes in the handle so you can put them in your pocket. I got a set on ebay for about £10.
A set of paints, with a pot of water that will all go in your pocket is easier than you would think..
I will ramble on about this if I get time.
