1 If your old style tank becomes water logged, the pump will run frequently or not turn off at all. There are two ways to fix this.  You can shut off the pump and drain the tank, then turn the pump back on and restore the service.
Yardage: In the gauge listed above, each granny square will require approximately 32 yards of yarn. In the photo above and in the video, I change color every two rounds. For a 42â square baby blanket, 49 granny squares, changing color every two rounds: â¢ Color A (center of square), 220 yards. â¢ Color B, 588 yards. â¢ Color C (becomes border color for each square), 760 yards.
You would need to cast on 150 stitches. The number of rows per inch will help you determine the number of rows you need to knit before you are finished. If there are six rows per inch and you want your blanket to be 42 inches long then you multiply 6 times 42 and you get 252.
