Embroider sprinkles (French knots) on frosting with pink yarn
Assembly...
Cut a circle of cardboard and glue it in the bottom of the cake. This will make it flat, and will also prevent your needles and pins from poking all the way through the pincushion.
Sew the frosting to the bottom of the cake with blue yarn, stuff firmly. Enjoy :)
