Ink the centers and edges of the petals before assembly. Use a ball tool or even the top of a ballpoint pen to gently shape the petals as shown in the photo. Curl the petals around a paint brush handle or wooden skewer.
To start constructing the flowers, push a brad through the hole in the center of the smallest flower, now glue the petals upwards around the brad – squeeze quite tightly, the more closed this center is, the more realistic the rose will look. Now add some glue around the hole on the second flower and thread onto the brad. Shape and curl as you go. Continue to add layers until you get the fullness you want. You can see in the photo that I made some buds, using just three layers, and adding a calyx.
