Fibonacci Striped Bag

BYOB - Bring Your Own Bag knitting pattern by Moira Ravenscroft, Wyndlestraw Designs

In my last few blogposts, I have been writing about the BYOB - Bring Your Own Bag knitting pattern with suggestions for fun variations. Today, I am going to feature a bag I made using all the left-over yarn oddments from other bags! The dyelots varied enormously, yet when this bag was finished you really couldn't see that there were any shade differences in the yarns. 

I have found myself really drawn to this bag and it has become my shopping bag of choice in recent times. It certainly has been the one most commented upon when I am out and about. 

The bag was worked completely in Seed Stitch and seemed to grow surprising quickly. I found myself saying: "I'll just work one more band..." and then before I knew it, it was finished! There is definitely some merit in having such frequent colour changes to provide a good target for your knitting! 

Fibonacci diagram for blogpost by Moira Ravenscroft, Wyndlestraw Designs

The striped pattern is a "Fibonacci" sequence. This is where the previous 2 numbers are added together to give the next number in the sequence, so: 

1+1=2, then 1+2=3, then 2+3=5 and so on to give the sequence:

1, 1, 2, 3, 5, 8, 13, etc

Fibonacci sequences give very interesting results, and reflect patterns we see in nature such as the growth pattern of a shell, the number of petals on a flower or the leaf structure of a tree. The diagram above, for example, shows the growth pattern for a mollusc shell. 

In this bag, I just used the 5 - 8 - 13 part of this sequence to form the stripes. So I worked: 

13 Rnds in MC, then 8 Rnds in CC#1 and 5 Rnds in CC#2,
then I went back to 8 Rnds of CC#1 again.

I had a lot of yarn tails to finish off at the end because I had used so many remnants, but it was very satisfying to have so little wasted yarn at the end of this project. 

I hope you have enjoyed exploring the many variations from just this one pattern. Please see my blogpost: "Bags of bags" where you can see photographs of all these various bags on one page, together with some of my other bag patterns.

I'll be back next time with information about a lovely cosy rug ready for the winter ahead.

Happy Knitting! 



  1. Thank you for BYOB. I am enjoying working it with "stash" yarn. It is larger than I imagined it but that is good. I am from MA also.

  2. I love this bag and can't wait to start it!
