To make willow pliable for weaving, it first needs to be soaked in water (you can use your bath or the special soaking bag provided in your kit).
Buff willow (light brown toffee colour) is great because you only have to soak it for a few hours before your can weave with it.
Brown willow is willow in its natural state with the bark still on. Ours has a beautiful dark green colour but there are many other varieties/colours you can use.
It takes longer to soak in your bag (a few days) but the process is extremely easy and we've found that overall brown willow is a bit easier for beginners to work with. The rods bend more easily round corners and are less likely to snap. It's also very hardwaring and looks fantastic!
