In crochet there are two types of crossed treble; back and front.
To do the back crossed treble:-
1. Put even number of stitches on the hook.
2. Row 1 In the second chain from hook do a single crochet on all the stitches.
3. Row 2 Make four chains. *Skip one stitch and make a treble crochet in next stitch. Put the yarn over the hook two times and slip the hook behind the current treble crochet and then insert the hook from front to back in skipped stitch. Finish the treble crotchet. Repeat from * to the end. Make a single treble crochet in the last stitch of the row to get an even finish.
4. Repeat Row 3 to make a pattern.
