The yarn for this design, Kauni Effektgarn, is available in the UK from scandinavianknittingdesign.com.
Kauni Effektgarn is available in the UK in 140g, 150g and 160g skeins, not 100g as printed in the pattern. You will need 3 x 140g skeins for this project.
Each ball of Kauni Effektgarn is unique so colours will not appear in exactly the same order as they do in the published images. It may be worth swatching a few entrelac squares and adjusting the point in the colour repeat at which you wish to start your tiers.
