Blanket:
150cm x 190 cm (59 x 75in)
Cushion:
50cm x 50cm (19¾ x 19¾in)

The squares are knitted flat and then seamed together, before a garter stitch border is picked up and knitted around the edge of the blanket.

For this I would recommend a 4.5mm circular needle at least 100cm (40in) long.

Yarn requirements:
2 balls each of Hayfield Bonus Aran in shades Black 965, and 813 Croft Grey
2 balls of Hayfield Bonus Aran Tweed in shade 749 Magpie
This is enough to make the blanket and the cushion cover. If you only want to make the blanket you will need two balls in Magpie and Black and one ball in Croft Grey.
If you only want to make the cushion cover you will need one ball of each yarn.
You can make a plain cushion cover using one ball of Hayfield Bonus Aran.
