Probably the most well known Estonian stitch is the Nupp bobble stitch. This bobble style is traditionally used in lace patterns for Estonian lace shawls from Haapsalu but also provides a nice bit of texture when combined with other stitch patterns for a modern look.

You can try out this technique in the following patterns from Aleks Byrd's book Traditions Revisited: Modern Estonian Knits:

- Rukkilill
- Mulin

The swatch shown at the beginning is the swatch for the Mulin sweater.
