Jim, I get the bags in bulk for my seed collection company. I am in Ellensburg, Washington. I can sell you some if you are interested - a couple dollars a bag to cover shipping and handling. They are about a gallon in size. I could probably part with 100 or so. I use quite a few in my own collecting. I just take some string along with me. It is pretty quick to tie them on the stem. I tie a bow like a shoestring so I can easily take them off. I tried the cloth nylon but I kept losing seed because it wasn't in the form of a pouch and I would inevitable let go of a corner or one side. Back at the farm, I can look through the bags to see what is in there. Much like the plastic bags that were mentioned but they get to hot and humid for me in the field in the sun (I work with a lot of xerics here in the sagebrush steep of the Columbia River Basin). Still, I like the idea of being able to zip them shut if they will stay with the stem in the seam. > Go to any large fabric store and you will find mesh fabrics in all sizes of > mesh. Making the bags could not be simpler for anyone with a sewing machine. Jane! Tarzan no sew. What is muslin? You are a life saver. I have been looking for different sized sieves. I did not know where to look. And when I called the manufacturers of the screens, they quoted me some high prices and I had to buy way more than I needed. This info will help me greatly. Wanna free nylon seed bag? ahhhh EEEyaaaaaaaaaahh Eyaaah Eyaaaah EyaaaaaAAAHH! Sorry. Politics have really been getting me down lately and I just had to let lose.
