This holds the silk in position.

Then fold or turn one end of silk back on the other piece of silk and knit one stitch of cord to hold them in place, always keeping silk on one side, on the top of rug, as this rug is not reversible.

Continue in this manner until one row is finished.
Then knit once across plain with cord, and for next row lay silk scraps in and knit as before.

Always knit one row of the cord across plain after knitting in scraps of silk, as doing this holds them firmly in position.

Of course, Mary, you will use judgment and taste in combining light and dark, bright and dull colors.
