Here I got to experiment with the cloth modifier again. At all points during this project I was trying to make everything to the highest standard. This meant that whilst modelling these sheets, I was trying to give them the most natural hang possible. After a brief period I realised that this would mean animating the points that the cloth is hanging from, so that they moved closer together whilst the cloth modifier was running. This gave the cloth a natural achievable hang.
These were then backed together creating a normal map.
