Resin Art Class RSVP Website: Mold Counts, a Vent Seat, and a Cure Line
A resin art class RSVP has to lock a mold and a vent seat before the resin is mixed, because a maybe does not hold a mold.

A resin art class breaks when the studio mixed resin for eight molds and twelve people are at the benches, or when someone who said maybe arrives after the pour and expects a mold that is already curing. Molds, the number of vented seats, and the cure line you agreed to are set before the first cup is mixed. The studio does not mix another batch because a friend decided to come after the mold count closed. A maybe does not hold a mold.
You can create a resin art class RSVP that fills the molds the studio will mix for, records who can sit through the pour, and stops when those seats are full.
Ask what the studio will actually mix
Call the studio before you send the link. Write down the session you are buying, how many people that session holds, what the mold is, whether resin is mixed to the headcount, how long the class runs, and when a cured piece can be picked up. Those numbers are your cap. Do not guess from the number of cups on the shelf.
A mold is one person, not one pair sharing a coaster and not one table. Ask whether a second project is a second mold and a second price, and whether a later session uses a different bench count. Pick one session and write it on the page. If you are doing both an afternoon pour and an evening pour, those are two lists with two caps. Do not mix them and sort people out at the door.
Ask the price, whether gloves and pigment are included, and the last time you can cut the count without paying for resin they already portioned. If they charge for a no-show after that time, print that rule on the page. Resin that was mixed for your session cannot go back in the jug.
Set a capacity limit on people who will pour, not on everyone who was invited. When the last mold in your session is taken, the form should say the class is full. A friend who might come still needs a mold and a seat the studio staffed under the fan. If the studio has already counted your group, they are not in this pour.
The cure line is a yes or a no, not a vibe
Ask the studio what the piece needs after class: stay on their shelf overnight, be demolded the next day, and be picked up in a window they name. Put that on the page in plain words. Each person confirms they can leave the piece and come back in that window, or they do not take a mold. A wet piece does not go home in a car.
If the studio will not ship a cured piece and will not hold it past the pickup window, say that. People who cannot return in that window should not take a mold. You do not need a speech about schedules. You need a yes or a no before the resin is weighed. A request to take the mold home wet should not be on the form.
Fumes, a tall stool, and a pot life that will not wait
Most resin rooms run a fan and seat people on tall stools at a high bench. Ask about the room as it is: a lower chair if one exists, or a clear note that every work seat is a stool. Collect seating preferences only for seats the studio actually has. If the only door is up a flight of stairs, say that.
Ask what the room smells like while resin is uncured, and whether drinks are banned on the bench. People who cannot sit in that room should not take a seat. You do not need a diagnosis. One color set is not a second mold. Collect an arrival window that matches the mix, not a vague afternoon. The window might be 1:50 to 2:00 at the studio door. Write the clock time and what happens if someone is later than that: resin has a pot life, and a person who misses the mix does not get a pour. A batch that already kicked does not wait for one car.
The moment the mold list is locked
The meeting point is the studio door they assigned you, with the room name if there is more than one. Put the host's phone on the page for the person holding the reservation. A screenshot of the invite is not a mold. The person at the door matches names to the count you sent.
If you allow a guest, that person needs their own mold line, their own cure answer, and their own arrival window. Track them as a separate yes. One form that hides an extra pour will blow the studio's cap and the resin weight for that session. Say that on the page. Write the age rule next to the question if the studio set one.
Tie your RSVP deadline to the studio's final count, the day they portion your resin. After that, a late yes is a call about a cancellation, not a promise of another mold. If you want names ready when someone drops, keep them as standbys and tell them they do not have a mold until you write back. A maybe does not hold a mold.
Export the list the morning you lock: attending or not, pickup window confirmed, seat, party size, arrival window, and phone. A resin class RSVP is finished when every mold has a named person, the cure line matches a shelf the studio will actually keep, and a late car knows whether they are pouring or going home.
