I designed these patterns myself. The first 4 photos are for cushion inserts of 36cm by 36cm. I haven't posted the 45cm x 45cm design yet, but it's on the way. The yarn is Panda soft cotton chunky available from Crossway shopping centre in Subiaco WA for Aus$7.00 (or $7.99 from Spotlight) a ball and you need at least 4 balls (6 is easier, but it leaves spare yarn) and 25 circular knitting needles. I am a reasonably fast knitter, able to watch Judge Judy more or less at the same time, and these take me about 2-3 hours. I am happy to answer any questions as you're using the patterns. I haven't done this before, so your feedback would be helpful. Not sure if this site lends itself to that - never etsied before either. I am also selling the finished product - see other products with Etsy. Pattern 1 is the white cushion with blue ribbon - a rib pattern. Pattern 2 is a skinny cable, pictured in the main picture and in blue yarn. Pattern 3 is the single off centre cable, pictured in pink. Panda soft cotton chunky yarn also comes in mint green and a tan colour... easily googled.
