Left over yarn and Domino knitting

I had some leftover yarn from some mittens, and decided to experiment a bit with the principles for Domino knitting.

First square - 29 stitches in yellow.
Knit one row.
2. row knit 13 masks, slip one mask, knit 2 masks together. Pass slipped stich over the "two masks", knit 13 masks.

Then I have used the Three center masks to reduce the number of masks with two.

Change to red.
3 row. Knit 27 masks.
4.th row - knit 12 masks, reduce the centre three masks to one as described in row 2. knit the next 12.

Continue till you have finished a square.
Make 4 more squares and join to one big square.
Make an extra square to make this wrest warmers.
