I love cutting out letters, it's fun to do and just looks so nice! I haven't really used it in my snailmail yet, but recently I started. A few suggestions of what you can do with it:
> Like my example cut out the 'dear <name receiver>' and 'love <your name>'.
> Cut the name of the receiver out of the envelope (don't forget to glue something on the inside!)
> Create a card
> Create a poster with a nice quote
> and so on...
I created a tutorial/manual for you guys how to cut the letters, what the best order is and a few tips.
Download in English or Dutch. Enjoy!
