Step 4: Make your flowers
I topped a piece of stiff wire with a small white bud off a plastic flower bunch, then I sliced a bright yellow plastic pedal into strips and glued them to the underside on the white bud in a circular array. I used another plastic vine-like clipping and attached it to the stem to give the flower some depth. I also managed to find blades of plastic grass which will be set used when the flower is set in the thimble.
Use your creative license, maybe even go a little crazy.
