How to weave putiputi (flowers) from harakeke and the tikanga involved in harvesting and using harakeke.
A harakeke bush
Knives or secateurs or scissors
A mat or ground sheet (to make it easier to collect up off-cuts and return them to the bush)
Background information, tikanga, harvesting and a karakia from https://my.christchurchcitylibraries.com/harakeke/
Weaving instructions from https://my.christchurchcitylibraries.com/making-a-putiputi/
Unfortunately I no longer know the source of the other two flower patterns.
