Don't know what the mesh is about but I use Ziploc also. I use the generic too. There are some bags out there that are big enough to put bedspreads in. I can't find my box. Anyway I save the silica packs you get in some medication bottles and put those in to absorb any moisture. Some of my hexies are in Ziplocs as take along while waiting in drs. offices. Then I have the project boxes that are the sizes of pizza boxes and are labeled. You can buy silica packets on line. they often are found in boxes of new shoes.
