I have a lot of sketches on loose bits of paper. Instead of keeping them hidden in folders or scattered around my studio I sew them into stitched sketchbooks. Not only do they look good displayed this way but I can organise the sketches into dates and subjects.
The sketches are from my local salt marshes. You can see many of these in my published salt marsh sketch books. Salt marshes are important and unique habitats so this is my way of telling people a little about them.
