The most complicated project was the tile-print cardigan. At it's widest point, it's circumference is 42 inches. It took 50 stitches to make 4 inches in width. How many stitches make up the full circumference of the cardigan

525 stitches

Step-by-step explanation:

The circumference is 42 inches

To stitch 4 inches, it took 50 stitches

Lets find stitches PER INCH, so we divide 50 by 4, to get:

50/4 = 12.5 stitches PER INCH

We have to cover 42 inches, so the number of stitches needed is:

12.5 * 42 = 525 stitches in total
