Washi tape: what it does, how it holds and when it comes off again
Washi tape is adhesive tape made from Japanese paper, named after washi, a paper made from long plant fibres. That is what sets it apart from every other tape in the house: you can tear it by hand, write on it and, in most cases, lift it off again without taking the surface with it. Once that clicks, you use it differently – not as glue, but as a design decision you can take back.
Which surfaces does washi tape come off cleanly?
Smooth, solid surfaces such as glass, paintwork and firm card. On thin or rough paper the top fibre layer can come away with it.
The tack is deliberately low. On a painted surface, on glass or on firm card you can still lift a strip hours later without leaving a mark.
The tricky case is thin paper – notebook pages, letter paper, old photographs. There the tape can take fibres with it. If you are unsure, press the strip onto the back of your hand once and pull it off: that removes tack and makes it noticeably more forgiving.
How do you tear washi tape straight?
Press your thumbnail against the edge of the roll and tear in one movement – do not pull. Use scissors when the edge has to be exact.
The tape tears along the paper fibres, across the roll. Pull slowly and you get a slanted, frayed edge; tear briskly and you get an almost straight one.
For edges that really must be straight – frames, tables, grids – scissors are still worth it. The slightly irregular torn edge is a stylistic device, but not one you want everywhere.
What does washi tape not stick to?
Dusty, greasy or heavily textured surfaces, textiles, and anything that is or becomes damp.
The paper needs contact with the surface. Woodchip wallpaper, fabric and anything grainy offer that only in spots – the strip looks attached at first and curls up at the ends a while later.
Moisture is the second limit. Kitchen worktop, bathroom mirror, fridge door: paper tape gives up there sooner or later. For those places the transparent PET versions are the better choice, being less sensitive.
How should washi rolls be stored?
Upright, dry and out of direct sun. Fold the loose end back on itself so you can find it again.
Rolls lying flat press themselves oval over time, and an oval core unwinds badly. Stored upright in a shallow box or on a rod they stay round.
The second annoyance is the lost end. Fold the last few millimetres back onto itself after tearing and you have a tab to grab next time instead of a minute of hunting with a fingernail.
Frequently asked questions
Can washi tape be printed on?
By hand yes, through a printer no. The paper surface takes ballpoint, fineliner and pencil well; in a printer the strip separates from its backing.
Does washi tape hold on photographs?
On glossy prints yes, and without residue. On matte or older prints use photo corners or adhesive dots instead – the surface can come away there.
Is washi tape waterproof?
No. Paper soaks through and the adhesive gives way. For damp surroundings the transparent PET tapes are the ones to reach for.
Can several strips be layered?
Yes, and because the paper is slightly translucent new shades appear where they overlap. From three layers on, though, the spot visibly builds up.
What width should you start with?
15 mm. It fits page margins, divides areas and can still be written on. Wider rolls are area rather than line.
