I'm in the same boat. Can't ordered online, too far to go get. I actually looked into making my own, but it was for bho not dry sift. The cost to make it didn't seem worth it to me so gave up investigating it. I will make a lift dry sift if I ever get any in a package tho. I have a cheap metal container with like a 160 micron screen on it. Won't be high quality, but press through a 25 micron bag slooowly and you be in good shape. I like to use all kinds of forms and methods, so I have some 1st hand

experience that I can draw from.
