High Fashion Sieves?
Stockings of assorted ‘gauges’ are flexible, washable (or cheap enough to throw away) and fine or coarse enough for most clay and glaze sieving needs. Tie knots at the top of the legs, then cut the legs off. The pantyhose section will also fit over a bucket for larger sieve batches.
