To make a rose first you have to shape some plasticine in the form of a petal of rose. After that apply vaseline on its surface and start arranging a long strand of bead over it in a spiral manner as shown. Then apply lacquer over the arranged bead strand and let it dry. When the lacquer has dried remove the petal and apply some lacquer on its back. For the centre of the rose do the same steps on a conical plasticine. Hot glue the petals around the centre to finish a rose.
