These toppers measure approx 1.5" These are printed on rice paper/wafer paper and are supplied in strips ready for you to cut out and use. There is no special skill to cutting them all you need is a dry pair of scissors. To get the best results place the topper onto icing or melted chocolate. Wait for icing to dry then put a light mist of water to stick the image down. Don't use to much water as moisture will cause the topper to wrinkle as they absorb water. The image will look better on a light coloured background this is due to the paper being slightly transparent and the image will stand out best on a white background.
