So with all of the engagement excitement and rush wedding planning, I completely spaced out and forgot about Valentine's Day

I'm in the process of getting everything together to send out to my fiancée even though I know it'll be late. I know I'm sending him a framed photograph of us from out first date and I want to send him "love" coupons that I made myself. I figured I could laminate them (we have a home lamination thing) and then whenever he hands one in to use, it becomes mine and I can give it back whenever I want. Sort of like an ongoing gift for the two of us. So, here's the question: I've already googled some good ideas for the coupons such as a 30 minute back massage, a 24-Hour no arguments coupon, complete control of the remote for a whole day, etc. but does anybody have any other cute ideas for redeemable coupons? I was also wondering if anybody's heard of the cake in a jar thing. Do you know if the idea of sealing it inside a mason jar would also work for cookies instead of a cake? Thanks for any help!
