And 9 blocks added together: I realised I had to keep my head together when creating this pattern, because did you notice that the order of the colours has to change to keep the repeating pattern going?This is the 'pattern' I made before I started:
Here is a close up of the edges where I joined the blocks together. I tried a few different versions of over-hand and ladder stitches before I was happy with these joints.
And of course I wondered if it possible to make the spiral go the other way... Yes it is, but you have to use your other hand and basically mirror the pattern by going around in the other direction. I am naturally left-handed but I crochet with my right hand because that was the only way my grandmother could teach me. With these mirrored blocks I used my left hand. It took me a while to get the hang of it! And it went very s-l-o-w-l-y... So I stopped after 2 blocks!
This is still a work in progress so keep a look-out for the finished product....
