Increasing with circular needles

I’m new with circulars and can’t figure out how to increase without the “hole”.

It’s the same as increasing on straight needles. Look at the videos for Increases, KLL/KRL are the most invisible and the M1A works pretty well too.

What type of increase are you using?

I don’t know why there should be any difference between knitting on circular needles… I just really don’t.
Can you describe your problem more detailed? Have you increased on straight or double pointed needles? Did you have a hole?
What is the difference with the circulars for you?
