Don't worry JaneQuilter, it will be fine!
The paint chips are a guide to hue and value, and you can stay close or range fairly far from the cards, keeping in mind that all of your neutrals should be lighter than your lightest aqua and coral, and all your aqua and coral should be lighter than your lightest brown.
The black and white photo helps you to see the actual lightness and darkness of the fabrics, without color to interfere with your perception of value. It looks like your lightest aqua and your lightest corals could be put with your neutrals. The most helpful thing would be to photograph all of your fabrics in the same photo, so a quick value comparison could be made.
