When I put away my tallis and tefillin, I do it in a way that I reach my talis first. Is it a problem if my talis is on top of my tefilin bag? The tefilin has more kedusha- does that mean they should be on top of the talis?
It is better that the tallis should not be on top of the tefillin, because a tallis does not have kedusha whereas tefillin do.
The tallis should rather be in front of the tefillin, and not on top of them. If there isn’t room, the tallis should at least not be squarely on top of the tefillin.
