I saw this idea on Pinterest and thought it was so cute. I changed it up a little and think it turned out great. The best thing is that you can trade out the heart for a different shape depending on the season/holiday.
All you need is a mason jar, a shape(I just cut out a heart shape from my scrapbook paper), a doily, and some ribbon. On the Pinterest pin they used baker's twine and it looked real cute too. I put this together in less than 3 minutes since I was rushing before the arrival of some friends.
