Can Non Catholic has the Lasso and Arras?

Hey everyone, I’m posting because I don’t see anyone else asking but my fiancé and I are thinking of doing the lasso (large Rosary) and the arras (13 coins) but we are not confirmed in the Catholic Church nor using a priest. He’s Hispanic and grew in the church though I’m not Hispanic and grew in a different church.

We are trying to figure out how much of those two are connected to the general Hispanic heritage and how much is strictly Catholic, since we don’t want to cross our moral lines.

Thanks in advance, please no debate that would fit on r/athiesm r/
