All the pictures of fabrics can be found either in the galleries or in the individual items listings.
These pictures are as accurate a representation as possible taking into consideration that colours can appear differently on different screens.
I cannot provide any further pictures of fabrics as not all fabrics are held in stock and due to my workload it takes too much time out of my day to assist with further pictures
If you wish to see the fabrics against a contrasting colour or lining then I suggest taking a screenshot of the fabric and using an app such as photo grid for a side by side comparison. I cannot provide this for you
