Loose sts on dpns

Hi guys.:grinning: I was wondering when I rip back a round on 4 dpns ,the loops of the sts are too loose?:face_with_raised_eyebrow:

Is there a way to tighten up loose loops of sts on the needles?
My tension is too loose on the needles.

What do you guys think ?:thinking:

It seems like it would be a constant problem to try to tighten sts at each round. I had trouble with metal dpns slipping out of sts but I solved it by going to bamboo dpns. They have just enough grab to hold onto the sts.
