I put a couple of swirls on the outside of the letter, continuing lines that existed on the inside of the letter. This is largely inspired by Yulia's work.
I hope you enjoyed this little tutorial! I had a lot of fun making these and it really became a matter of becoming comfortable with the paper and then it was kind of like a little click! Suddenly it was very simple! I highly suggest this craft as it is really satisfying and quite easy. If you like doodling this is going to be fun for you!
