If your toy is to be given to a small child you need to make sure that the features you add are safe and cannot come loose and be swallowed. Here is how I sew the eyes onto knitted toys.
1. When stuffing the head, leave a small opening either at the back of the head or at the base. Do not sew this up you have added all the features.
Mark where you want the eyes to go with 2 glass headed pins.
Thread a tapestry needle with black or brown yarn.
Take the needle in through the opening in the head (in this case my opening is at the base) and out again at one of the positions marked by a pin.
Remove the pin
Make a small stitch across one whole knitted stitch to prevent the eye burrowing down into the stuffing.
Work a french knot taking the yarn 2 or 3 times round your needle.
Secure the stitch by taking your needle back into the stuffing in the head.
Take your needle back up through the position marked by the second pin.
Make one stitch across a whole knitted stitch, as you did for the first eye, pulling the yarn tightly so that the knitting around the first eye indents a little.
Work a second french knot.
Take your needle back out through the opening in the head. Pull tightly on both ends of the yarn, so that indentations are created around both eyes.
Knot the two yarn ends firmly together.
.Don"t sew up the opening in the head yet!
