Looping is one of the harder styles to advance in, it takes a lot of practice so don’t be discouraged if you’re not looping in your first few days.
Unfortunately there’s no looping secret, it just takes practice. Try watching our looping tutorials and any other looping videos you can find.

Study their technique and keep at it, you’ll get the hang of it soon enough! ;D
And for the string: Cotton is a little thicker than the stock polyester string the loop 1080 came with, that’s probably why it isn’t sleeping as long. Stick to the polyester if it is working better for you.
