Cap it: six garments in, six tickets out, and a named destination for everything unclaimed agreed before the invitation goes out. The figure behind the cap comes from the EEA, which puts EU-27 clothing consumption at 6.0 kg per person in 2020 within 15 kg of textiles in total, and reports that the time a garment stays in use has fallen by 36% over twenty years, with each item worn an average of seven or eight times. The condition that changes the cap is the room: one rail and no seating works better at four items each than at six.

Why a cap beats a collection

A swap that takes everything becomes a sorting job for whoever booked the hall. A cap sets the volume the organisers can actually handle and tells invitees what to expect before they fill a bag.

The environmental case for the swap sits in the same EEA briefing, and it is about production rather than disposal: 80% of the climate impact of textiles falls in the production phase, 14% in use and 3% at end of life, and EU-27 textile consumption carried 270 kg of CO2 equivalent per person in 2020. A garment that gets a ninth and tenth wearing in another wardrobe is the part of that a swap can move; the number of purchases it prevented is not something the door count can tell you.

Write the invitation around who can come

State six things: the date, the venue and its access, how many garments each person brings, the condition accepted, how items are chosen, and where unclaimed items go. Ask about access needs privately, before the day, rather than in a group message.

Decide in advance whether someone with nothing to bring can still take something, and say so in the invitation rather than leaving them to ask in front of a room. If tickets are used, say what earns one and what an unused ticket is worth afterwards, which is nothing.

Set the condition rule from a charity's own list

Borrow the condition rule from a recipient who publishes one. Oxfam GB accepts clean clothing in good condition, including children's and out-of-season items, and shoes in pairs, and refuses anything broken, dirty, incomplete or unsafe, along with identifiable work uniforms. Using that as the swap's own rule means the leftovers already meet the standard of the place they are going.

Keep labels on where they exist, and write measurements on a tag where the label has gone rather than guessing a size. Arrange the rail so browsing does not need anyone to lift a pile or reach above shoulder height, and provide seating and somewhere private to try things.

Example: twelve people, six items each, one Saturday

An example. Twelve people bring six garments each: 72 items on the rail. If 40 go home with someone, 32 are left, and those 32 need a decision that was made weeks earlier, not at 4pm with the caretaker waiting. One person runs the door, counts items in and hands out tickets; the other keeps the rail tidy and manages the leftover boxes, one marked for the named charity and one for items going back to their owners.

The swap's paperwork is two numbers and one name: 72 in, 40 taken, and the shop that confirmed it would take clean clothing in good condition. When two people want the same garment, a short draw settles it, agreed before the doors open rather than invented on the spot.

What the leftovers are about to walk into

Textile collection in Europe is being rebuilt around this point. The Commission's targeted revision of the Waste Framework Directive entered into force on 16 October 2025 and requires every Member State to set up an extended producer responsibility scheme for textile and footwear products, so producers contribute to the cost of managing used and waste textiles. Mandatory separate collection of textiles was introduced in the EU in 2025; before it, the EEA recorded collection rates ranging from 4.5% in Latvia to 45% in the Netherlands.

None of that removes the organiser's job, which is to phone the recipient first. A shop with no capacity this month is a common answer, and it is easier to hear in advance than at the door with 32 garments. The enquiry itself is the same one described in checking what is actually wanted before donating.

Afterwards, record what was missing rather than what was lovely: the sizes nobody brought, the rule people asked about twice, the part of the room that was hard to reach. That is the planning sheet for the next one. The same cap-and-destination habit works for objects that are lent rather than given away, on a shared shelf of things to borrow, and it is worth being precise about what the day claims, because repairable, reusable and recyclable are different promises.
