Context: breakfast table, mc, and his sister and parents

I'm having a hard time relating not cooking at home with a change to an arts
and crafts club, let alone why everyone is a fit for wool felt.

After this his sister just says goodbye and leaves.

What is she trying to say?




  * She confirmed she was going to do "club activities of 調理部" in this morning.
  * But the club members no longer do cooking these days, and they are now virtually 手芸部. ( **EDIT** : This うち is an informal way of saying "our club (or office/team/class/etc)")
  * _Therefore, what she is actually going to do in the morning is not 調理 but 手芸._

The part after から has been omitted, but the omitted final part is the main
implication of her first sentence. (But how did you come up with "not cooking
_at home_ "? Is the club activity going to take place in their home, or did
she refuse to prepare breakfast this day?)

This ～にハマる means "to be caught up in ～" or "to devote oneself in ～".
