For this pattern to make one square you need:
Yarn: One 50g ball each of aran weight yarn in shade A and shade A. This amount is based on 100m per 50g.
Tension: 18 stitches and 24 rows to 10cm square over stocking pattern using 5mm needles.
Measurements: approx. 40cm x 40cm.
My design ideas and advice: The materials quoted are to make one square. One square is perfect for a cushion with a fabric back. If you wish ot make a cushion with a square on each side, double the amount you need. Or if you wish to make the blanket as in the photograph you need to knit 12 squares.
