SYOA - Chapter 3 - Runes

Yesterday, I only had about an hour to stitch so I started the Ancient Runes.  My runes will spell SYOA.  Stewart designed the whole alphabet using 4 colours (purple, blue, green and red) and I wanted to use all 4 colours.  Unfortunately, S and O were both purple, so I changed the O to be blue and now I have one of each colour.

This is the whole project so far.
