What you need:
Cut felt into small, 32 tear-drop shapes. Two of these should be half the size of the normal pieces.
Start by gluing and pinching the bottom half of the small petal. Then, glue all subsequent petals on the bottom of the teardrop shape, then glue in a circle around the 'flower', and widen the flower by gluing a little further from the center with each row.
Create a variety by experimenting with different petal shapes!
Tape up the glass while you paint the frame. When dry, start gluing the pebbles and succulents down.
