If you’re going to buy plastic crochet hooks, there’s something you need to know.
THEY WILL BREAK.
If you’re a very delicate crocheter, perhaps not. But if your enthusiasm comes out as furious speed-crocheting like me, you’re better off with just buying metal ones.
The reason to have plastic/wooden hooks though is travel. If you’re planning on crocheting on a flight, you won’t get past security with a metal implement in your bag.
The other reason is quite niche, but if you need to remove dreadlocks the plastic hooks are a lot nicer on the hair. I had to do this last summer: my advice is do not use a metal hook. It hurts.
