Trivet's revisited

 

We wanted to have another go at the trivet we made a few weeks ago, to see if we could improve on our first attempt. The main thing we struggled with last time was the edging. I think we were more confident this time but we still haven't figured out the perfect corner! Don't get me wrong, we managed OK corners but we just wonder if there's a knack to it that we haven't figured out yet! Answers on a postcard please!
