Answer 2

This question got cut off mid-sentence. The widest strips would be either 43" or 59" (with gain) or 36" cross grain. Surely, that isn't the question. In my experience there is always wasted fabric, because I can not cut perfectly. Play with the equations below for various width strips, to maximize what you need.

A) If you want ONE strip, cross-grain (that is selvage-to-selvage), the width on the bolt will be the length of your strip. Usually people trim off the selvage, so I'd say 43" (for 44-45" bolt), or <59" (for 60" bolt).

B) If you want ONE strip, with grain (that is running along the selvage), it will be the same length as the length of fabric you purchase. 36" for one yard, 72" for 2 yards.

C) If you want several strips, cross-grain, divide the inches you bought by the width of the strip (if you cut very accurately), to get the number of strips. 1 yd = 36" divided by 2" strips = 18 strips (17 if you are less accurate.) 17 strips times 43"/strip, less seem allowance to join them ... (17*43)-8 = 723" long.

D) If you want several strips, with grain, divide the inches in width of your fabric by the width of your strips to get the number of strips. 44-45" width fabric (43" trimmed) divided by 2" strips = 21. (half strips don't count!) 21 strips times 36" (per yard), less seem allowance to join them. (21*36)-10 = 746" long.
