Crochet Gif Tutorials: The Magic Loop
Aka: the magic circle, the magic ring, the adjustable ring, witchcraft…
The magic loop is my favourite method for the starting round when crocheting in the round, for projects like hats or amigurumi. The alternative method is to ‘chain 2, make x sc’s into 2nd ch from hook,’ but that will leave you with an ugly hole in the centre of your circle. The magic loop closes up completely, which is especially great for amigurumi - it keeps the stuffing from leaking!
You can also use dc’s rather than sc’s - so it’s great for starting granny squares, too.
