Making a Hem
A knitted hem which results in a double layer of knitted fabric, helps the garment to hang and fall better. The knitted hem is usually knitted on a smaller size needle than the main needle used for the garment.
Cast on the amount of required stitches (on one size smaller needles)
Beginning with a knit row, stocking stitch (knit one row, purl next row) the depth of hem required finishing on a knit row.
With a purl row facing, knit this row. This row now makes a ridge on the right side of the garment giving the hemline.
Change to the larger needles for the next row knit this row, then begin main pattern.
When garment is finished turn the hem under to wrong side and sew in place.
