The project uses garter stitch, picking up stitches and decreasing and I would say it is an easy project. There is some sewing up on this project but most squares are attched to one another by picking up stitches. Full instructions and diagrams are provided.
The yarn used is Rowan Felted Tweed in 6 shades, 1 ball of each.
This cushion has an approximate finished measurement of 45cm x 45cm.
 
The pdf pattern includes instructions for the scarf and the cushion.
 
This design is available as a kit, which includes the printed pattern and the yarn for the project.
