First time trying corner to corner style crochet. Had a 200g ball of 'rainbow' yarn to use up, it wasn't enough to make a whole lap blanket so I added the pale blue corner and then decided to add a herringbone border to make it a little bigger. I wasn't sure how I felt about the rainbow yarn, the colours change very quickly and it started to remind me of a hotel carpet lol but I think the blue corner really helps, it looks better than I was expecting - looks like it was the plan all along! 100g of the pale blue yarn which I doubled up to make the weight of the rainbow yarn.
