This tutorial contains a link to the Raindrops Stitch, to be able to make up the Rainbow Raindrops Cushion.

Yarns: Stylecraft Special Chunky yarn, worked on a 6mm hook, in eight colours as follows ::

♥ Raspberry ♥ Lipstick ♥ Fondant ♥ Camel ♥ Meadow ♥ Aspen ♥ Lavender ♥ Denim

There is enough yarn here to make two of these cushions, you only actually need 4 x 100g balls of chunky to make a 45cm cushion in this pattern.
