Crochet Trinity stitch tutorial

I thought I'd give a quick tutorial on trinity stitch.  I'll be using UK notation, for US notation simply change the DC to SC :)

It is made over any odd number of stitches (+1 for the beginning chain)

Starting with a chain of even number. 

DC into the second chain from the hook,
DC3 together by inserting the hook into the same chain that the first DC is in, draw up a loop, insert the hook into the next chain & draw up a loop, insert the hook into the next chain & draw up a loop.  You now have 4 loops on your hook, having worked into 1 preworked chain & 2 new chains.  Yarn over and draw through all 4 loops on the hook.
Chain 1

Continue as such across the chain until you reach the end.  The last stitch on the chain will form the last loop of a trinity.  In this case do not chain following the trinity, but instead DC into this last stitch.

For the next row;

CH1, DC into the last DC of previous row. 
DC3 together by inserting the hook into the same DC just worked into & draw up a loop, insert the hook into the next stitch & draw up a loop, insert the next 1CH loop & draw up a loop.  You will have 4 loops on your hook, having worked into 1 preworked DC & 2 new stitches's.  Yarn over and draw through all 4 loops on the hook.
Chain 1

Continue as such across the chain until you reach the end.  The last DC will form the last loop of a trinity.  In this case do not chain following the trinity, but instead DC into this last DC.

Follow this pattern.
