YARN, GAUGE, SIZE  AND MACHINE  These are designed for #4 worsted  weight yarn on any bulky or mid-gauge machine. The yarn must be soft to use #4 on the mid-gauge. The sample  socks are made from Encore Colorspun from Plymouth yarn which is  75% acrylic/25% wool. 1 skein made  the pair of socks shown which is the  smallest width and second length in the pattern. Adjust the stitch size to get a fairly  firm fabric at 5 stitches/7 rows per inch. Bond knitters can make these, probably using  the #2 keyplate. Ribbing stitch size will be 1-2 numbers smaller than stockinette stitch  size. Choose ribbing stitch size by what works well for the machine and makes a ribbing  that pulls in nicely.
