My Sweetheart Jar of Messages in Mini Envelopes
Another sweet idea. You could always make your own jar of messages as well. Find your own jar, decorate it yourself, and find a creative way to put messages in there. I do like the mini envelopes idea. You can write a bunch of things you love about your partner, and you can put secret messages in there. This might even be an interesting way to ask someone if they will marry you. One of the messages could be that special message or something like that.
