Design for a hand woodblock printed textile, showing the complexity of the blocks used to make repeating patterns in the later 19th century. Tulip and Willow by William Morris, 1873. Woodblock printing on textiles is the process of printing patterns on fabrics, typically linen, cotton, or silk, by means of carved wooden blocks.
A wooden mesh in which the withes were one eighth of an inch wide and set the same distance apart. This would be used on an English farm of the Victorian era to sift grain, removing dust and soil. The mesh in a wooden sieve might be made from wood or wicker. Use of wood to avoid contamination is important when the sieve is used for sampling. [3]
In printing, wooden blocks, stencils, engraved plates, rollers, or silkscreens can be used to place colours on the fabric. Colourants used in printing contain dyes thickened to prevent the colour from spreading by capillary attraction beyond the limits of a pattern or design.
A riddle is typically used to improve soil quality by allowing the gardener to sieve through soil and remove stones, twigs, large lumps of clay etc. and hence provide a finer tilth. Smaller riddles can be used to separate soil very finely for seeds and early potting. Riddles may also be used to help remove soil from harvested vegetables.

Tulip and willow design for printed textiles (1873) William Morris (1834-1898), a founder of the British Arts and Crafts movement, sought to restore the prestige and methods of hand-made crafts, including textiles, in opposition to the 19th century tendency toward factory-produced textiles.
Before the mechanization of papermaking, paper was made by hand, using a wire sieve mounted in a rectangular mould to produce a single sheet at a time. A papermaker would dip the mould into a vat containing diluted pulp of hemp or linen fibers, then lift it out, tilt it to spread the pulp evenly over the sieve and, as the water drained out between the wires, shake the mould to lock the fibers ...
The grain, either coming through the concave or the walkers, meets a set of sieves mounted on an assembly called a shoe, which is shaken mechanically. The top sieve has larger openings and serves to remove large pieces of chaff from the grain. The lower sieve separates clean grain, which falls through, from incompletely threshed pieces.
