Capillary mats are so expensive! Even at Charley's - the price is decent, but by the time you add the shipping it's right back up there. I saw the clever system with yarn in the pots, but I have a couple of Park Seed biodomes, and that wouldn't work in those. I've always wanted ot try the mats. Has anyone used any other type of fabric successfully? I've seen comments about cotton, felt, and wool blankets, but no info on how it worked out.

I used old towels and diapers someone successfully as wicks for outdoor container plants when I as traveling...would those work as mats, or would they be too soggy?
