My MIL and a group of her friends have offered to through me a shower that is out of town. The way my MIL described it it sounded like several people, including her, are all helping to make it happen. I would imagine that the person who is having the shower at her house will be the real host. Would it make sense to just do a thank you note/gift to person who is throwing the shower at her house, or should all the ladies in the "helping" group get a thank you note?
