I know I didn't need any fabrics, but I like to visit a relatively new shop that is in Rose Green when I visit my parents in Bognor Regis. It is only small but has a good selection of bits and bobs, you can see that I also bought a thimble and some scissors.
She has a good stock of the Makower and Tilda fabrics, and I really couldn't decide what I wanted so just bought a selection of 'craft' cottons which I thought were just as nice.
She has a facebook page:

Across the road there is Rose Green Centre for Art and Craft that offer a selection of courses, and has paintings and other crafts for sale:
