A short video to show how to work a corner join with double crochet stitches in mosaic overlay crochet (US terminology). I've used this join in the border of my Lavender and Lace Pattern. I apologise for a mistake around 10.41 mins when I say slip stitch but should have said stitch marker. The Lavender and Lace pattern has now been released. You can find it here:
