Have been reading my KG magazine today and found this great use for plastic drinks bottles. They advertised it for picking gooseberries but I will use it next time I have to prune my thorny hedge and go picking blackberries, I always end up getting prickled.
Cut the top and bottom off a plastic bottle, slip the bottle over your hand and onto your forearm. Now your forearm is protected from wrist to elbow and won't get prickled.
