Another craft kit or extras idea. The little heart tags are cute, but with Christmas tree stamps, this could easily work for wrapping Christmas gifts. I would like tags stamped with a few different shapes, so you could use this for gift wrap year round.
Self promotion idea. I know this may be unusual - but if your brand needs some updating and "fun" this idea may be just for you. Collect bow ties at thrift stores and put them on your portfolio/packages/ create a bow tie graphic for your biz card etc.
