I've been asked a few times now, how to trim my handmade paper and still keep that soft torn deckle edge effect, so here's my approach.

As you can see from the video, it's easy peasy : ) Just fold and wet along where you want to tear (paper needs to be well soaked), and make sure to gently tug the paper to the side - not upwards. Then leave to dry for beautiful feathery edges!
