Yes, I agree. That's clever to use that material! We've just cut out squares of old door/window screen. Works great, except for the wee wee teeny seeds on occasion that I have tried.Also, for sprouting with canning jars, I use a circle cut out of that bumpy plastic shelf liner material (I don't know how else to describe it!) and insert that with a canning ring over the jar for drainage. Easy. I have also seen people use craft needlepoint screen, same thing...
Have fun! There are so many options...I looked on craigslist the other day and found a 50# bag of whole oats for $10 from a local farmer.
