From the description: Recycle your old shopping and bread bags into a little mat that’s light and flexible, eminently washable and great for outdoor use. When you think about how long it takes for this material to break down in the tip you’ll understand just how tough this mat will be, yet it is surprisingly comfortable and soft underfoot - or under your knees in the garden.

Requirements:

• plastic bags cut into continuous strips 1-1.5cm wide
• large crochet hook (8-12mm suggested)
