Mystile

Once the decision was made to use and modify a pre-made theme, I looked through the internet to find a good low cost one that I felt could be changed into what I wanted. I ended up back in WooThemes like most of the tutorials I watched had and the theme I picked was called "Mystile", this theme is very plain and simple, its clean and easy to use and the main thing that I wanted was for it to be responsive and I have tested this theme to check that it is.
The reason I chose such a plain theme is that I want to make it my own, so getting as close to a blank canvas as possible but avoiding having to try and code the PHP, this theme seemed like the best option. WooCommerce is the addition to this theme to make it a shop which is exactly what I needed.
Here you can see what the theme looked like as a demo, but when you get this site it is completely blank for you to customise yourself.

The only downside to this theme is that because it was free you are not allowed to take off their branding on the bottom. However for all the plus sides this theme has come with, I can live with their watermark.
