A little tutorial about cutting out corduroy. Corduroy has surface texture which is referred to as the "nap." If you run your hand along the fabric in one direction it will feel like you are stroking a cat. If you run your hand in the other direction it will feel like your are rubbing the cat in the wrong direction. If the top of the pattern pieces don't all face in the same direction the garment will look like it is made out of different color fabrics. I was taught to have the nap running down and just assumed that was a sewing rule. I was recently looking through a sewing book published in 1964 which stated that the nap of the fabric should run up so that the fabric will have a deeper color. So just like that, I found that there is not a set rule and we can do what whichever we prefer!
A few days later I was getting ready to cut out red corduroy for a Christmas outfit and was not totally happy with the color. The red just wasn't quite red enough. Fortunately I remembered that there is no longer a "nap rule" and when I turned the pattern pieces in the other direction, the fabric was a deeper red and did not look as washed out. I often tell my students that there are few right or wrongs in sewing, but many different ways to do things. This time that saying worked to my advantage. :)
Which direction were you taught for the nap of the fabric to run?
