There are times when a small brush comes in handy for sweeping flour off the griddle or for basting a haunch or even sweeping some ground and this is a simple little item to make.
Cut a handful of soft (field) rush and have a little nettle cordage to hand to bind them
Bind them tight around the thick end of the rush, it doesn't have to be neat, just functional
Trim the top into a dome so it doesn't stick into your hands and cut the brush end to the desired length
and once it's complete you have a very versatile and efficient little brush for many different tasks.
