Something I do and I usually tell students is to open the fabrics up a bit and lay them on your bed. This way the choices will be a further apart. Leave them for the day. Every time you walk into the room, note which side you are drawn to, what appeals to you more. Both of these fabrics work, but for different reason. A problem that many of us get into is that we get into our head and overthink things. Go with your gut - which one pleases you and makes you smile.
