I don't have my own shop, however some of my designs are available on products at Spoonflower and HappyWall.
Spoonflower is a US company that offers printed fabric, wallpaper and home products. There's a big choice of designs in many colours and sizes!
HappyWall is a Swedish company specialized in wall murals. They sell a few of my designs as wallpaper.
