I sorted MIL's cards last night. there weren't as many as I thought, so there must be another box somewhere.
I need to put her cards on hold because they smell like smoke so I need to air them out before I put them in something. The living room smelled awful last night when I was done! I'm going to put them in a plastic bin with a bar of soap and seal it up for a few weeks, that usually works.
I'm going to work on my cards instead but I have 17 years worth of wedding, anniversary, bday, and holiday cards! That's gonna take some time! But one advantage is that we date cards (got that from Grandma) so I can get those is order pretty quickly. I hope to start those tonight.
ETA: and there apparently will be journalling when MIL's friends wrote on the back of the card, I'm going to type it out next to the card because some are really hard to read.
