I am sending out magnets for my save the dates and I was wondering if it would be OK to send ONE magnet to each household. For a few relatives we have elderly family members living with their children or adult children still living at home. I will send a separate invite to each person/couple when the time comes, but I was wondering if it would be OK to just send one magnet addressed to everyone at the address for the save the dates. It just seems excessive to send 3 magnets to one household. Would this offend anyone? Would it be better to just send one to each person? Thanks!
