Statement Necklace OR My First Pattern Hack

I found this pattern.  Then I decided it worked but could be better.  I wont link it just because I don't want to say that this particular pattern is bad.  Its just not exactly what I was looking for.

So, I wanted to make it what I was looking for.  

I'm not a big fan of math.  So when I realized that I was about to embark on the most math intensive project of my life I was a little hesitant.  

The problem is that you don't know if it works or not until you are done.  Until the last stitch.  It took me about 4 hour to break it down.

I realized that the pattern is 4.  There needs to be a multiple of 5 double crochet.  To get a multiple of 4 loops.  But there is a turning chain so that makes one less chain than there will be double crochet.  BUT to make the side symmetrical you have to put 3 double crochet (or two loops) in the same stitch.  Then you have to have three rows of dc on the bottom layer, 2 in the middle and one on the top.  

Yeah.

So this is basically my pattern...

Bottom Layer
1 - ch 20
2-4 - ch2, dc into 2nd ch from hook and dc across (21)
5 - ch5, dc in same st as the ch *ch3, dc in next* rep 19 times.  Ch3 and dc into the same stitch to create 21st loop in the same stitch as the 20th looop. (do not use turning chain)
6  - ch3, *tr,ch,tr,tr,tr,ch,tr, (Into first loop) ch3, sk loop, sc into the next loop, ch3* Repeat * to * until the last loop.  tr,ch,tr,tr,tr,ch,tr, ch3 (into the last loop) sl and tie off

Middle layer

1 - ch 16
2-3 - ch2, dc into 2nd ch from hook and dc across (17)
4 - ch5, dc in same st as the ch *ch3, dc in next* rep 19 times.  Ch3 and dc into the same stitch to create 21st loop in the same stitch as the 20th looop. (do not use turning chain)
5  - ch3, *tr,ch,tr,tr,tr,ch,tr, (Into first loop) ch3, sk loop, sc into the next loop, ch3* Repeat * to * until the last loop.  tr,ch,tr,tr,tr,ch,tr, ch3 (into the last loop) sl and tie off


Top layer
1 - ch 12
2-3 - ch2, dc into 2nd ch from hook and dc across (13)
4 - ch5, dc in same st as the ch *ch3, dc in next* rep 19 times.  Ch3 and dc into the same stitch to create 21st loop in the same stitch as the 20th looop. (do not use turning chain)
5  - ch3, *tr,ch,tr,tr,tr,ch,tr, (Into first loop) ch3, sk loop, sc into the next loop, ch3* Repeat * to * until the last loop.  tr,ch,tr,tr,tr,ch,tr, ch3 (into the last loop) sl and tie off

Then I added the chain.  Use the left most and right most chain stitch the attach the chain.   

WHEW.
