Step 1: Material:
- Fabric for the main body of the cell -I used flannel
- Toy stuffing
- Embroidery thread
- Pins and needles
- Template for organelles (see celltemplate.pdf below)
You can use a sewing machine to attach the larger organelles, but the smaller ones may need to be hand stitched. I mostly used hemming stitches and in some cases running stitches along the edge of the felt. Click here for examples of these stitches
Step 2: Cell body
Step 3: Nucleus, Nucleoli and Chromatin
The nucleus is a membrane bound organelle that holds the cells DNA.
The nucleolus is the site of ribosomal RNA synthesis.
Chromatin consists of DNA and its associated proteins.
- Cut out a large circle of felt, this will be the largest component of the cell; the nucleus.
- Cut out a circle of felt in a different colour with roughly 1/4 the diameter of the nucleus, this will be the nucleolus.
- Cut out several little 'X' and 'V' shaped felt pieces of a third colour. These are the chromosomes(chromatin).
- First sew the nucleoli to the nucleus.
- Then sew the chromosomes onto the nucleus.
- Then sew the whole thing to the the cell (that blue piece of fabric from step 2).
