Absolutely stunning basket! Love it. The screen idea was brilliant. I sometimes use an old piece of double knit material. One other thing I do in baskets such as these is to line with a single layer of a garbage bag with several tiny holes punched in it with a small nail, which could help keep the soil in, but more importantantly, let's the water flow through more slowly, therefor wetting the soil more fully when watering, giving plants a better drink. This method has served me very well for many years.
