Reply To: Why a Bigger Yarmulka is a Better Yarmulka

A bigger cappel is hiddur mitzva, like a bigger esrog. The point is to remind you about Hashem, so the bigger it is the more it reminds you, hence it is a hiddur.
If it looks nice its Zeh Keili ve’Anveihu. Probably a black velvet one is better i this respect than “a huge green and purple knitted” one.
But of course the most important thing is that it should have a rim. Joseph didn’t ask about the importance of the rim because its so blindingly obvious.
