Flea markets and jumble sales in the Yvelines (78) are kicking off toy sale season this weekend, November 7 and 8, 2026. On Sunday, half a dozen villages, from Jouy-en-Josas to Dammartin-en-Serve, are opening their community halls for secondhand toys and stuffed animals.
Two events offer something a little different: the Montesson autumn-winter clearance sale, running over two days, and the Saint-Nom-la-Bretèche sewing flea market on Sunday, for anyone with a head full of sewing projects.
On our outings around the Yvelines, the first weekend of November often has the same feel. The big outdoor flea markets have packed away their trestle tables, and parent associations are stepping in with tables piled high with board games and puzzles to complete.
On Saturday, November 7, and Sunday, November 8, 2026, from 10 a.m. to 6 p.m., the Montesson-accueil association is holding its autumn-winter sale at the community hall. It works on a consignment basis: residents drop off their items the day before, and the association handles the sales.
You’ll find coats and sweaters, as well as shoes, leather goods, costume jewelry, tableware, home linens and a few toys. It’s the only event in the département that opens on Saturday.
On Sundays, from 10 a.m. to 5 p.m., the AVF of Saint-Nom-la-Bretèche holds a sewing supplies fair at the JKM Center. Fabric by the yard, yarn, lace, embroidery thread and sewing accessories are sold there by both private sellers and professionals.
The exhibitors’ tables are fully booked, a sign that the event has its regulars. A refreshment stand offers a chance to take a break between two pieces of linen.
In Dammartin-en-Serve, the events committee is holding its 12th toy sale from 9 a.m. to 4 p.m., with a carousel to keep the little ones entertained while their parents browse. In Plaisir, the sale at the Salle des Gâtines accepts only complete items in good condition for children aged 0 to 16.
Near Versailles, the Jouy-en-Josas toy fair brings together families from the town and Les Loges. In Morainvilliers, the youth council is running the Broc'aux jouets, open only in the afternoon, from 2 p.m. to 6 p.m.
Further south, Orcemont is hosting a toy and baby goods sale from 9 a.m. to 6 p.m., near Rambouillet. In the north of the department, Jambville is hosting a toy and clothing sale from 9 a.m. to 4 p.m.
On Wednesday, November 11, a public holiday, Trappes is holding its autumn flea market at the Jean-Baptiste-Clément Hall, with 50 to 100 vendors. On Saturday, November 14, Guyancourt is holding its toy fair at the Joseph-Kosma Center.
Sunday, November 15, is for collectors, with the 20th Poissy Multi-Collectibles Fair and the Beynes Collectors’ Fair. The full calendar can be found on Brocabrac and Vide-greniers.org.
Parents looking to fill Santa’s sack without breaking the bank have plenty to choose from on Sunday, from Plaisir to Jambville. Sewing enthusiasts can head to Saint-Nom-la-Bretèche, while anyone looking for a winter coat can stop by Montesson. Showers are possible this weekend, but fortunately most of these events are being held indoors.
