Using a flat brush, determine the width of the rosebud by making 2 vertical lines to use as your guidelines. Double or triple load your brush with a dark color and a highlight color.
Position the brush so that the light color of paint is at the right side of the brush. Make the top of the bud first. Position the chisel edge of the brush at the left.
Pull brush into a curve, ending at the opposite guideline with the brush up on the chisel edge.
Make the lower "U" shaped section of the bud by starting on the chisel at the left guideline.
Pull brush in a curve to opposite guideline, ending on the chisel edge of the brush. Make another layer of the bottom stroke, positioning stroke just slightly lower than the first.
To make the calyx, double load the same flat brush with your leaf color and highlight color. Start with the chisel edge at the base of the bud.
Lean and pull the brush and lead with the lighter edge of brush as you pull stroke along the side of the bud. Do not bend the wrist, but pull arm.
End the calyx on the chisel edge as you lift the edge of brush.
