Darlene is a 60-inch blanket, made with Stylecraft Special DK and a size 4mm/G hook.
Approx 3735 meters/4077 yards of yarn needed.
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 happy colours version was made with 7 colours.

For the pink version you need to order:
2x Clematis
2x Magenta
3x Pistachio

For the happy colours version:
4x Sunshine

You can find both colorways and the amount used per round listed in a separate pdf.
If you stop after round 59 you will have a baby size blanket of 38 inch/ 95 cm square. For baby size you need approx 1564 meters / 1707 yards of yarn.
