Capillary mats for seedlings

I'm growing far more seedlings myself this year than previously and found that self watering trays work best for me.

Now I wonder what else I could use instead of purchasing capillary mats or getting back to making felts. Felting is a nice activity in winter, but for us here in NZ it's springtime and faaaaaar too busy in the garden.

Has anyone ever tried old bed linen, old sweaters or anything?
