Houndstooth Crochet Pattern

Work due to the scheme, on which both right-side and wrong-side rows are stated.

Crochet first 3 rows with violet colour, and 4 next rows (they're stated red on the scheme) with light-green colour. 

Repeat 1st -7th rows.

* 2 chain stitches, yarn over, insert the hook in first square and draw the stitch, repeat yarn over twice and draw the stitch. Then make yarn over and insert the hook in lower square (see the scheme) three times and draw the thread. Then, yarn over and insert hook in the third lower square, then in fourth, fifth. When all slipped sts from each square will be on the hook, draw the sts through all sts and fasten it with slip stitch. Make 3 chain sts and 3 double crochets.
