This is a new stitch for me, and I am very pleased with how it has worked out.
Adapted from a pattern that I bought on ebay (search Hot Water Bottle & Cushion Covers Crochet Pattern Basketweave)
It is made in Robin double knit shade 59 (Moorland) on a 6mm hook, and took just over 100g to make this 12″ cushion cover. The wooden button was hand made by Terry Hitchen in Lochcarron.
