Thanks everyone. I'll consider all. I used to use sheets for backs so this wasn't a problem but I have ventured out of the box trying new things and like the patterned back! In this particular case..there is a directional pattern...herd of horses running through the meadow..the pattern repeats top to bottom but my problem was width. I can cut it in the middle but that would break up the path the horses are running. and to add on each side the same fabric would do the same so I think in this case I just have to add borders to each side.
