I must be a little kid at heart because I love these little Valentine blocks, just listed in my shop. I created them last year and haven't had time to create more this year, much to my disappointment. These are tiny, just 1-1/4" square, smaller than the vintage Christmas blocks I had in my holiday shop.
They are upcycled from solid oak newel posts left over from my new staircase and I purchased some of the images from an Etsy shop, Picturemerchants. I created the lettering myself.
Here's some sample views.
