This kit contains all yarn and full pattern instructions to make this cushion, you can choose to make the cushion in the Ocean or Aurumnal colourway. The cushion is pictured in the Ocean colourway. 
The project uses garter stitch, picking up stitches and decreasing and I would say it is an easy project. There is somw 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 which is a mix of 50% merino wool, 25% alpaca and 25% viscose and can be washed in the machine on a cool delicate wash (please follow ball band instructions). This yarn is a firm favourite with knitters and crocheters alike, great to use with it's soft tweedy texture and also a performs well for years to come.
This cushion has an approximate finished measurement of 45cm x 45cm.
