Couple suggestions -
**ask at LQS for ideas - they usually can find companion colors if you find 1 special fabric you like.
** use the color dots along selvage to match coordinates to a fabric you like
** don't fret too much - a scrappy quilt or log cabin can look terrific with large variety of fabrics
** and finally, quilts with just a few colors are sometimes more soothing & pretty than ones with too many colors! Enjoy the process & don't worry about too few colors.
