MAIN PURPOSE: Weave patterned bands with turning cards
A pack of 64 mm square cards with a hole in each corner labelled A to D: thread four warp ends through each card, then turn the stack forwards or backwards to twist the warp and weave patterned bands. Printed cards stay flat and smooth where cardboard frays and catches threads.

MAIN PURPOSE: Build adjustable boxes for silicone moulds
Four identical L walls with one arm set a wall's thickness further out: rotate each by 90 degrees and every inner arm slides inside its neighbour's outer arm, so the four make any mould box from 60 to 180 mm square. Clip the overlaps, seal the base with plasticine and pour silicone or resin.

MAIN PURPOSE: Dip several pairs of taper candles evenly
Lay the comb across the dipping can and drop a looped wick into each V notch, where the slit pinches it: five pairs of tapers hang at an even 30 mm spacing, so they never touch, and every dip goes to the same depth. Lift the whole comb to dip and hang it on two hooks to cool.

MAIN PURPOSE: Comb floating paint into marbled paper patterns
Twenty-six tines at 10 mm spacing on a 260 mm bar: drag it through paints floating on size and the stones break into the even nonpareil and wave patterns of traditional marbled endpapers. Pins pushed into a strip of wood bend and snag; printed tines stay straight and wash clean.
