This is an incredibly sweet idea. "Open when you need to know how much I love you; open when you don't feel beautiful; open when you need a laugh; open when you miss me; open when you're mad at me; open when you need a date night, etc.
I'm in the process of doing some Open When cards for my long distance boyfriend. Here are the titles of each card I'm making. I also decided to do one with the answers to some of the puzzles I'm putting in a couple of them. (: <-- this sounds amazing.
Gifts for each hour of the day. This is a cute idea for anniversaries, birthdays, valentine's day, etc. Pinner did this for wedding anniversary. So 3 min. Past each hour I have him a little gift. The gifts don't have to be anything really expensive.
such a sweet idea (Start writing things in this starting from when you get engaged and give it to him the night before the wedding for late night reading that will leave him more excited than ever to wake up the next morning.
