Questions about tattoo symbology

[rurounihime]

Hi, all my folks who have some experience with symbology or tattoos (or both)...

My sister and I are looking to get matching sister tattoos. We are representing both sides of our family: English-Irish and Norwegian. The tattoo design we have in mind at this point incorporates the Viking Vegvisir compass and an Irish sister knot. I just want to check in with people if they know if this is a legit sister symbol in Celtic knotwork. The most prominent ones I have found are this one or variations on the theme.

Another option I like is this one, but I'm leaning toward the three-pronged knot just because I've always liked sharp, defined edges.

Thoughts? Tips?

The plan is for the tattoo to go in the center of our upper backs, between our shoulders just like the one you liked. Though it has to go on hold for a bit because I just paid $500 to fix something in my car. Oh well. Gives me time to really dig in and get the design I want.
