Cordelia is a 60-inch blanket, made with Stylecraft Special DK and hook size 4mm/G.
Would you like to make it bigger, there are directions given in the pattern to repeat some parts.
You need approx 3181 meters/3472 yards of yarn.
Should you choose to use a thicker yarn and larger hook, your project will of course be larger in size, and you will need more yarn.
The pink version used for the tutorial is made with 5 colours.
The bright version is made with 7 colours.
You can find both colorways and the amount per round listed in a separate pdf.
