In this category you’ll find various tangle and doodle patterns. Some will be step-by-step tutorials, others just variations of patterns I’ve seen elsewhere on the internet (in these cases I’ll post links to the site where I found the instructions).
A couple of patterns you can use a reference.
Here is a pattern that is very useful as a border. How to draw the basic pattern is shown in steps 1-4 and then I’ve done some variations. In the first one the shading is done with a regular pencil. In the next two I used a liner pen with a finer tip to draw on the inside. The basic outlines I did with a Faber -Castell PITT artist pen Size S (which I think is roughly 0.5) and for the finer tangles on the inside – a 0.1 Uni Pin Fine Line.
