2x1 Item Duplication Glitch

This glitch has been patched in the V 1.2.1 update and does not work anymore.

A glitch has been discovered by players for the second time around in the game's V1.2 update, which was shared in a Youtube video by user Artificial Switch. This allows you to create several copies of any 2x1 miscellaneous furniture inside your homes. Miscellaneous furniture are items that can be placed on top of tables.

Take note that this is a glitch not intended by the developers and has been fixed with a game update.

A first duplication glitch was discovered back in March, and was immediately patched in the V1.1.1 update.

Steps to Mass-Duplicate 2x1 Items

If you want to take advantage of this glitch while it's still around, you have to do certain steps. We recommend this method as it is the most efficient way to duplicate as many copies of the items in one run.

This is a recreation of the video Twitter user @TPOE_ACNH shared.

What You Need
  • 2x1 item to duplicate
  • 2x1 table
  • (Multiple) 1x1 tables
  • Empty room in your house
  1. In an empty room, enter Decorating Mode by pressing the Down Arrow button.
  2. Place the 1x1 tables next to each other, making sure there is 1 space around them.
  3. Place the 2x1 table on the ground, and the 2x1 item on top of it.
  4. Grab the 2x1 table, and place it over 2 small tables.
    Place it in a way that the table will the item will be rotated when placed.
  5. Keep repeating the last step to guarantee duplication of the item.
  6. Exit Decorating Mode, and leave and enter the room. Depending on how you did, you will get at least 1 copy of the item.
  7. Enter Decorating Mode to put the items in the storage.

1. Enter Decorating Mode

In an empty room, press the Down Arrow button on your D-Pad to enter Decorating Mode.

2. Place the 1x1 tables next to each other

Place the small tables on the ground, making sure that there are exactly 2 spaces around them (enough for a 1x1 item to fit).

In our test, we used 7 tables; one is actually a stool, and the other one is a wardrobe, but it still works because you can place items on top of them. This means that most stools and chairs will not make copies of the item, since you cannot place items on top of them.

3. Place the 2x1 table, then the 2x1 item on top of it

Place the 2x1 table on the ground, then the 2x1 item to be replicated.

4. Place the table with the item over 2 small tables

This step is crucial, and will determine the success of your item duplication.

While pointing at the 2x1 table, press the L button to swap layers. Do not use the R button to grab the objects.

Press and hold the A button to drag it over 2 small tables. When you drop it, it should rotate.

Keep repeating this step to guarantee item duplication.

6. Leave and return to the room to see the copies of the item

Exit Decorating Room, and exit the room. This will give the copies an opportunity to load into the game..

Go back to the room, and depending on how well you did step 5, you should have at least one copy of the item.

7. Enter Decorating Mode to put the items into storage

Now, you cannot manually pick the items up. You will need to go back into Decorating Mode, and press the Y button over the items to send them to the storage.

How to Fix Bugs

Cannot Pick Up Item

If you cannot pick up an item, duplicated or not, with the Y button, you need to enter Decorating Mode by pressing the Down Arrow button, and store the item instead by pressing the Y button over it.

Cannot Place Item on Table

If you cannot place an item on the table, it means that there is an "invisible item" on top of it. Leave and enter the room again to reveal invisible items.

To make sure, try moving around the table, or add tables around the room so invisible models will appear on top of them.

Item Missing or Gone

If you find yourself losing items along the process, one possibility is that the item model is just "invisible". Try placing tables all around the room to reveal "invisible items".

If this does not work, it could be possible that your item got deleted in the process of recreating this glitch, so only do this at your own risk!

Patch Updates

Patched in the V 1.2.1 Update

As of May 21, 2020, a new update is available to download via the Internet, which fixes all the glitches found in the V 1.2.0 update of the game.

Punishment and Repercussions

“Fixed a serious bug affecting game balance.”
Source: Nintendo's Patch Notes re: V1.1.1 Update

It seems like they have patched the method to recreate the glitch, but not the glitch itself. I happen to have a table glitched on the latest patch with a fish model dupable. Granted it was glitch pre patch, but I can still get infinite models to sell so I'm happy.
