I am a bit confused by your statement about saving it and not cutting off.
If you are using it to border, you will need 4 repeats of any one of the strips you will use. You didnt say how much stripe fabric you have and how large your wallhanging is. If you will tell us these two things then I can give a more informed answer . size of center of wallhanging and yardage of your fabric and how many repeats across the strip fabric.
