Javis foliage bags are amazingly versatile... from tearing off tiny blobs to add next to fences or buildings, to sticking down large chunks as proper hedges - We love these.
Some of the 'big brands' hedge foliage is really foamy and tricky to stick down - The Javis product is much stiffer and will easily stick down with a touch of PVA. For realistic hedge areas mix a couple of colours.
