These robust hanging basket liners are made of 5mm thick felted jute. These are great because you can re-make them year after year. What I find with a lot of the shop bought ones made with a natural woven outer and plastic lined inner is they look great when you buy them, but only last a season and look really shabby whatever you try and do to rejuvenate them the following year. And what do we hate at Chimney Sheep? We hate waste of course! So using these biodegradable liners with wire framed baskets is an excellent way of making the basket last year after year, and you can have all the creative fun of making your own hanging baskets.
