Start with a canvas tote and raffia in 3 shades. Using a disappearing-ink fabric pen, draw circles on tote, 1 for each sunburst (ours are 1 1/2 to 5 inches in diameter).
Mark the center point of a circle (A) and 1 point anywhere along the circle's edge (B). Thread a large-eyed needle with raffia in desired color, knotting it before embroidering design using a French-knots-on-stalks stitch.
Draw needle up through A. Wrap raffia around needle 3 times. Holding wrapped portion together, gently draw needle down through B, forming French knot.
Repeat step 3, always coming up through A but moving B 1/4 inch over, until the sunburst is complete.
Make matching pom-poms to trim a straw hat. Using a pom-pom maker and raffia, make a pom-pom (ours are 1 1/2 inches in diameter).
Wrap center with floral wire, twisting wire with pliers to secure. Trim wire to 1/2-inch. Repeat to make more pom-poms, using raffia in different colors.
Then attach to hat with embroidery thread.
