Black plastic sheeting for weed suppressing (Bailbrook)

This is not the woven, water permeable sort that you can cut & plant in, but a waterproof sheet to cover areas of garden to suppress weeds over winter to prepare for spring planting. I have enough to cover about 12 square metres in different sized sheets. Used, so a bit muddy! Will split.
Update: some has been collected but still one large piece and 2 smaller pieces left.
