A Proper Pattern for a Fibonacci Seashell **



Here is photo of completed model, crocheted with the right hand in one direction and with the left hand in the other direction,  to make an even surface.  Directions will soon be posted.

This is the real thing.

Today I am repeating some data from posts subsequent to this one.  You have to scroll upwards to newer posts.  I am continually making repeat models, and have trouble remembering exactly how I do them.  I am 70 years old.........all the clues are given....it is not good to spoon feed info  to people.....better for folk to figure out for themselves!  
To date there have been  898 ...pageviews of this post.  Thus  I am making eforts to explain it better.







the little point up top is not necessary.
it was just me trying to figure out the shape.
You can see it is complex.  Three different areas vertically. Not easy to type up a normal crochet pattern.  Sewing up I later stitch it from top right, outside face, in a spiral moving down so that it is a right hand spiral, with the wider opening on the right when you look at the underside of the model....

Update 16/4/2014

1.     You might like "Instructions for Making a Model of a Seashell",  given at the very beginning of this blog,  plus a gallery of many different models, crocheted and knitted.    5/25/2010  or 25th May 2010.
The Pattern is in accordance with the Fibonacci Series of Numbers  where .....8+13=21,  13+21=34, 21+34=55, 34+55=89.   To work the Pattern we use  34=2x13+8, 55=2x21+13,  89=2x34+21  etc.

2.     The Pattern for this new Seashell depicted in this post of 2012 here is completely different from the 2010 models.  Here the basic Pattern is 4 stitches become 7   or 13 stitches become 21.  The diagram explaining it is at "Crocheting the Vortex"  4/28/2011.   I made the mistake of assuming that people were aware of this when I made this "A Proper Pattern" post....  click on image to enlarge it.



3.     This present Seashell was first announced in "Time Flies" of 11/22/2011.  Related posts were in 5/26/2011.
Then we have "A Proper Pattern" of 1/19/2012  (this one),  "On the Trail of the Fibonacci Snail" of 3/19/2012  and "The Seashell Model" of 2/24/2012,  especially visual instructions for making this present model in "Now it's Getting Closer to the Real Thing" of 2/24/2012,  then some more work....trial and error...

4.     See "Internal Structure of Seashells" of 5/4/2013 to understand the complexity of the shape.
Also "Real Seashells" of 5/4/2013,  "The First 135 Fibonacci Numbers" of 5/4/2013  and "Diorama" of 1/31/2013

5.     Most recent work is happening on "The Real Seashell Updating" of 2/3/2014  and "Adding Time and Space" of 2/1/2014  which gives another way of displaying the Pattern (an easier one) and it discusses variations.   The most recent model, a black and white one is being attempted.  It has some improvement in making the knob on top,  but still it is not yet perfect:  a work in progress 4/16/2014

 It definitely is all a process of trying something and seeing what happens.  You can use any kind of yarn you like,  and any size needles or hook you choose.  The UK/Australia  vs USA  have different gauges and different names for the stitches,  and it is hard to spell it all out exactly.

Adding,  5/6/2014

A new model as close as I can get to the "Proper Pattern" of this post has  been made.  Text for Pattern is being typed.  I called the pilot model a "proper pattern" in the sense that it is more like the real thing than the models I originally made in 2010.

The problem with a blog is that one reads backwards, that is , downwards.  To access newer info one must scroll up dates on right hand side of top pages to see ongoing work.  I noticed that I have worked on this model for two more posts immediately,  and there I mentioned the differences in stitches for crochet in UK/Europe/Aust  vs USA  plus size needles and hooks differ.  I am putting new tables to explain better how to increase and decrease Pattern to achieve Fibonacci series numbers used in this project.

PS see post 12/26/14 for "Information for US and UK Crocheters"  for full data.

This above model here is too hard to write up.  One needs to be able to crochet with left hand and right hand to have an even outer surface with no ridge.  Plus the shops selling fine crochet cotton yarn---they no longer stock these,  or have closed!  Our world is becoming poorer in some ways....

I had a go at crocheting her model, and I thank you, Susan.  The bumps are really nice.
34 stitches max.
