S/L1 This is really good quality Lycra in great colours. In our experience a Lycra creates loads of movement, plus much laughter. Pull it, stretch it, send someone underneath to make shapes, bounce a Koosh Ball or Lycra Buddy. You can probably find this fabric cheaper, but this will stay looking good and it's strong enough to really safely support the play. It's what we use.
Robust, super-stretchy fabric square. 182 x 155 cms
