There are many different ways to knit with beads. We will go over the way that is used in Lithuania when knitting garter stitch wrist warmers.
The patterns are charted. Plain knit stitches are either white or the color of the yarn being used. Bead stitches are indicated by a square that is black or the bead color.
Only WRONG SIDE rows are shown on the charts. I’ve created the charts to be read from right to left. (The bead charts in Lithuanian books are read from top to bottom and the standard for reading the wrong-side rows on English and American charts is from left to right, but I have found both of these conventions to be confusing to knitters in my workshops.)
Work a RIGHT SIDE row with no beads, then work the charted WS row as follows:
Bead Row (WS): Sl 1 kw wyif for a slip-stitch edge (optional). Do not count this stitch. Knit the plain stitches normally. When you come to a black square on the chart, slip a bead up to the needles and knit the next stitch, pulling it tight to hold the bead in place. This counts as one “bead stitch.”
The bead sits between two stitches on the needles and will naturally go to the back of the work, which is why we knit in the beads on the WS rows.
