I didn’t realize dry sift could be so cheap and simple to make.
Basically i put the trim into a bucket.
I put a 150 micron screen over it, i picked the screen up from ebay £4
Nylon Mesh Food Grade Filter Net Micron Fabric Cloth Kitchen Oil Water Colanders | eBay
There’s a 1x1 square it’s enough for 4 uses/shakers and some.
Fix it around the the top of the bucket then shake it over a sheet of plastic.
Scrape it together and bag it.
Enjoy!
