ok so your fabric is 60" wide, but i'm assuming the selvages are 1" each, so you have 58" cuttable
when you use corduroy you have to make sure you cut the fabric across the nap in the same direction, or else your garment ends up looking as if its made of different shades
this might be an issue with your yardage
what size are you going to make?
for reference
a medium mens chest is about 40"
it's a bomber, so you have 2 fronts, 1 back piece, 2 sleeves
1 rib neckline or 2 collars
1 front piece = 11" (Seam allowance included), and the center front to hem length is probably about 26 1/4", 24 1/4" with a 2" rib hem
1 back piece = 21", and the center back to hem length is probably 27 7/8", 25 7/8" with a 2" rib hem
1 sleeve = most likely 17 1/2" wide, and 27" long, 25" if you have a 2" rib cuff
assuming you cut your fabric correctly, and lay out
patterns efficiently
you'll use somewhere between 51" (1.4 yards) and 55" (1.5 yards roughly)
these are rough estimates off generalized numbers, but i'm sure you'll be fine
a better estimate would be to measure
front width= across chest(flat part at bottom of armhole) for each piece
front length= high point shoulder to hem
back width = across chest for each piece
back length = high point shoulder to hem
sleeve width = cap line (flat part of sleeve cap curve, widest part of pattern)
sleeve length = measurement down the center of the sleeve
you take these numbers
draw a graph in inches with the y axis as length of the fabric, and the x axis as the width, and plug in squares as symbols of the pieces with their corresponding measures
this helps you know before purchasing fabric how much you need, i usually buy a 1/4 to 1/2 yd more
