Cerebrum

This is the final part in my series of patterns to make a life-sized anatomically-correct human brain. I have tried to make it was accurate as possible to the gyri and sulci in a real brain. The blood vessels are optional.










Difficulty:

Medium
The trickiest part of this is pinning it in place correctly

You will need:
  • A 2.5mm crochet hook
  • 3 balls of anchor creativa fino 4ply cotton in pink
  • Polyester toy stuffing
  • Red #10 rico essentials cotton
  • 20-30 safety pins
  • Crocheted inner brain structures (optional)
  • around 20-30 yarns scraps of varying colours

Note:
  • 'Fasten off neatly' refers to a special way of fastening off which is neater and makes it easier to see where you should be crocheting on the next round (also known as invisible fastening off). This involves pulling up your yarn through your stitch, threading the yarn underneath the second stitch from where you pulled your yarn up, then threading your yarn back through the top of this stitch and down through the back of the work. There is a very helpful site that explains it clearly found here. Just make sure when you do this that you thread your needle through the SECOND stitch after the last stitch you made, otherwise you will end up with an extra stitch which may mean that all of the following rounds are out of line with each other. The false stitch that you create is referred to in this pattern as the 'new' st.
  • Put differently coloured markers on each round with *** so you can work out which one is being referred to. You can remove these once they're referred to in the pattern.

For the right hemisphere:
using the 4ply ch12

Pin into position. You then need to sew this side together in the same way as you did for the right hemisphere.




Sew all of the sections that you've pinner together, and add the blood vessels in red. Sew the temporal lobe in place so that it overlaps with the other brain regions, as shown below





Finally sew the two hemispheres together, as shown below

  1. My God! You must be the most patient person in the world because I would have a stress crisis with all that work. It's magnificent! My most sincere congratulations for your work and, above all, for your stratospheric patience. Thanks for sharing. A hug...
