This cast on is used to provide a stretchy cast on for 1 x 1 or 2 x 2 ribbing for socks, mitts or hats. The Estonian Cast On is a version of Long Tail Cast On; the difference is that with the Estonian version the yarn loop on the thumb is reversed for every other cast-on stitch.
Continue, repeating Steps 2 – 12 until desired number of stitches has been cast on.
