It's lovely knitting baby clothes and there always seems to be a steady demand for hand-knitteds despite the ever-growing supply of manufactured clothing.
Making little jackets is quick and easy. You don't have to stick to the predictable pinks and blues these days. Why not try knitting one in Dad's favourite football colours? Be as progressive as you can and you'll find yourself a popular market product.
It's still always worth knitting up a good stock of the old-fashioned styles and pastel shades though - they are still a popular choice!
