Used large carpet for allotment? (Horspath OX33)

Large used woolen carpet, pinkish beige in colour, hessian backed. Approx 4.6 metres long by 3.8 metres wide, there’s a cutout for a hearth so slightly longer at one point. Not in perfect condition due to children's paint antics etc (whoever claimed kids paint is fully washable was very wrong) and soot spillage from chimney on removing a stove so best for weed suppression on an allotment or lining under a pond?. Prefer this to go this week or I'll have to take it to the tip as I can't store it. Collection only from Horspath as I can't deliver, be aware it's heavy and cumbersome in its current form
