Crochet: four-double treble.
In this DROPS video we show how to work quintuple treble/five-double treble. Wrap the yarn round the crochet hook 5 times =6 loops on the hook. Insert hook into next stitch, yarn over, pull up a loop. There will be 7 loops on the hook, yarn over, pull through 2 loops on hook 6 times = 1 st on hook.
