I hope I have given you enough time to knit up that swatch and get things rolling a little more. At this point, you should have completed the swatch and measured it. So far we have the following numbers:
11 sts x 16 rows = 2 inches
9.5 sts x 21 rows = 2 inches
Next step: please measure around the ball of the foot of the person who you are going to be knitting the sock. Check out this link on how to measure your feet, you want to do #4 on the list.
Once we have the gauge and the measurement around the ball of the foot, we can more accurately calculate how many stitches to cast on.
For example: my foot measures 8.5 inches around and I got a gauge of 9.5 sts=2 inches. You can do the math two ways: Divide 8.5 inches (measurement around the ball of the foot) by 2=4.25 x 9.5 (multiply that by the stitches per in, 9.5)=40.375
Divide the stitches in the 2 inches by 1. 9.5/2=4.75 then multiply that number by the measurement around the ball of the foot. 4.75 x 8.5=40.375
Socks are knitted at a negative ease so they fit snugly around the foot, the negative ease that we typically use for socks is around 10%. From the number we arrived at, 40.375 for my foot, we are going to decrease 10%. I round up or down so I am left with a multiple of 4 of the necessary multiple for the sock pattern. In this case, I am rounding down to 36 pegs.
Okay my dears, now it is your turn. You have your gauge, now measure your foot and see if you can calculate the number of pegs needed for your socks. If you can’t, no worries, post in the comments the following: Gauge, measurement of the ball of the foot at widest point and then say HELP ;).
I will come by tomorrow, Thursday to get us going in the right direction with the number of pegs to use for our sock.
