See size charts for amounts
dk / weight 3 yarn I used Womens Institute DK Shade navy (250 metres per 100g) for the main colour and for the contrasting colour I used Stylecraft Wondersoft Merry Go Round Shade 3154 Pastel Rainbow (294 metres per 100g

If using a main colour and contrasting colour I would estimate that you would need 3/4 main colour and 1/4 for contrasting colour eg: 400 metres would be 300 metre main and 100 metre contrasting colour.
