Purl side increases

I have a pattern (sweater) that instructs you to increase on both ends of a purl row. I am not sure which is the proper way of increasing either with a yarn over or M1. Can someone please help.

You could use a M1purl:

Which pattern are you following? Sometimes, if it’s all the same, I move the increase to the knit side. Sometimes you can’t do this but if you can it may be easier.

Thank you so much for the video. It looks like this is the easiest way to make the increase. Have a great holiday weekend

Great! Happy 4th to you and everyone.
