These cute botanical coasters will be amazing for any home and will bring a cool spring spirit inside! Prepare pressed leaves, 350g block of white polymer clay, a crystal resin kit, a rolling pin, grease proof paper, glass / cup, a scalpel, a baking tray. Preheat the oven to the recommended temperature on the back of the clay packet. Split the clay into quarters and then roll each section in to soften them up and create four balls. Then on the greaseproof paper, roll each one out with a rolling pin roughly a quarter to half a centimetre thick. Place your glass on top (gently) and cut round the circle with a scalpel.
