The case

We've had reports of some children having to wear very uncomfortable jumpers.

Here we test materials to find out which ones are best for certain jobs.

View all the tests to decided which of the materials would be best to make your jumper?

  1. Must be stretchy
  2. Must pass the twist test so it can easily be made into strong strands
  3. Must be soft and comfortable
