What I most like about traditional Portuguese embroidered handkerchiefs is the concept: an embroidered message, usually written in verse, and illustrated (or not) with symbolic images of the message being said. So you can easily adapt this concept to any occasion.
Last year, when she said yes, my special gift was this handkerchief wishing them all the best in their new life together as husband and wife. It was inspired in this beautiful story about life and hope, where a red line connects the whole story.
PS: The baby boy is almost here. All they need now is a dog.
