Willow domes are easy to make.You need to measure the height of your willow withie which are sold to you in bunches.That will tell you the radius of your circle. Dig a sircle in the ground and using a metal bar and a mallet make as many holes as you need for your willow. You need to cut the bottom of each withie to encourage growth as well. The hard bit is really weaving everything together and you need to watch someone doing this. You can then make your own. I made these in different schools and will shortly be helping four schools to make theirs.
