Kintsugi Workshop RSVP Website: Shard Counts, a Bench Cap, and a Lacquer Line
A kintsugi workshop RSVP has to lock a shard set and a bench before the first lacquer, because a maybe does not hold a shard set.

A kintsugi workshop breaks when eight benches are set and fourteen people arrive expecting a shard set, or when the ceramic order was built for eight and three of those names were still a maybe on Friday. Shard sets, the bench each mender uses, and the lacquer stage you will actually stop at are set before the first join. The host does not open a ninth set because a neighbor decided to mend after the sheet closed. This is kintsugi, broken ceramic rejoined with lacquer and a metal powder line, not a pottery wheel class and not mosaic tiling. A maybe does not hold a shard set.
You can create a kintsugi workshop RSVP that fills the benches you will actually set, records who is mending and who is only watching, and stops when those seats are full.
Count the menders the benches can hold
Walk the shop before you send the link. Write down how many benches have a clamp or sandbag, how many pre-broken ceramic sets you prepared, and whether a spare set is a replacement for a piece that will not join or a ninth project. If eight benches can each take one mender, that number is your cap: eight menders, not a crowd sharing one brush.
A kintsugi station is one shard set, one bench, and one lacquer kit. You clean the break, brush on lacquer, join the pieces, and dust the seam with gold or silver powder. There is no spinning wheel, no wet clay, and no tile cutting. Ask whether a person who will not mend can watch from a stool away from the lacquer, and whether that person still counts toward the number the shop can hold. Pick one rule and write it on the page. Watchers stay off the shard set. They do not take a turn with someone else's brush or start a second bowl "just to try."
Ask the last time you can change the ceramic order without paying for sets you cannot return. If the supplier locks the order on Monday for a Saturday shop, that Monday is your lock. Write the finish too: one set, one named mender, brushes cleaned when the seam has reached the stage you named. A ninth bench "if a clamp frees up" is not a plan.
Set a capacity limit on mending seats, not on everyone who was invited to watch. When the eighth seat is taken, the form should say the workshop is full. If the sets are already prepared, a late mender is not at these benches.
The lacquer line is a stage, not a vibe
Name the piece you will finish and stop there. A clear line is one small dish or cup, a single break line, and a stop at "joined, dusted, and set aside to cure," not a multi-day polish to museum gloss. Rebuilding a shattered vase with ten fragments is a different workshop, and you will not finish it in this block of time. Throwing a new bowl on a wheel is a different class. So is mosaic, with cut tiles and grout.
Put that stage on the form as the point you will stop, not a vague "until it looks finished." If the class ends when the seam is dusted and curing, that is the line. People who want to "keep refining until it shines" will still be polishing when the shop has to close. You need a yes to this set, this bench, and this lacquer line before you hand out shards.
Who can work the bench, and who to call
Workshops go wrong when the bench is a surprise. Kintsugi means sitting for a long stretch, handling sharp edges, and working with lacquer that needs ventilation. Ask whether someone needs a seated bench with arms, gloves in a larger size, or a station away from strong scent. A guest who cannot be near lacquer fumes does not get assigned the bench next to the open jars.
Ask about accessibility needs before you assign benches: a chair instead of a tall stool, a clamp someone can tighten, and a path that is not blocked by a ceramic cart. Collect an emergency contact for each mender, because a shop with sharp shards and lacquer is not a living room. Write what happens if someone misses the start: their set goes to a standby already in the shop, or it stays on the shelf and the late guest does not begin a second piece.
The moment the sets are locked
The meeting point is the shop you named, not "the studio" with no bench marked. Put your phone on the page. A message in the group chat is not a bench assignment. You match names to shard sets.
Tie the deadline to the ceramic order, the day the mender count cannot change. After that, a late yes is a call about a cancellation, not a promise of another set. If you want names ready when a mender drops, keep them as standbys and tell them they do not have shards until you write back. A maybe does not hold a shard set.
Export the list the morning you lock: attending or not, which bench, accessibility note, emergency contact, and phone. A kintsugi RSVP is finished when every bench has one named mender, the lacquer line is the stage you will actually stop at, and a late guest knows whether they are mending or watching from the stool.
