All about Outlining
I think an outline looks great on most pieces and you can get different outcomes depending on how you choose to loop your string.
1. The most simple way is around the outside of the nail, around once and move onto the next nail.
2. You can also go inside the nail for a different look.
Mix it up to match your pattern.
3. If you want the line a little thicker wrap it around nail 2 and back around the nail 1. Take it back up and secure it by wrapping it once around nail 2.
4. If you are working on something that needs a thick line then you can go for these two options.
The first image shows the previous outline followed by a crisscross pattern.
The second image shows the same thing, but with another layer of the outer and inner outlines.
This is great for doing writing.
