I made a bunch of these cards for my own personal use last Valentine's Day. I am making more to send to OWH for this coming Valentine's Day. I have made them the same way except for this year's cards, I am adding the "I Love You" sentiment. The challenge for ODBD is to dust off a rarely used tool. I have had this stamp for a long time, and only used it once last year. I think that qualifies as "rarely used."
I am also entering it as the MWTD for OWH.
