The plain envelopes looked like this:
You can easily open them using the cover of a pen or even the handle of a spoon.
I chose my favorite Hey Kessy washi designs and lined them starting from the flap crease.
I was on a roll and lined a whole pack of envelopes! Here are just four of ’em. Now, they look simple, but not boring, and of course, craftier!
I will definitely make more of these :p
