To re-fluff a Squishmallow, start by removing any packaging. If it comes vacuum-sealed, let it sit for a few hours to allow the stuffing to expand.
Next, place the Squishmallow in a pillowcase and wash it in cold water on a delicate cycle. Adding fabric softener can make it even softer. Dry it on a low or no-heat setting with tennis balls to help fluff it up.
You can also fluff your Squishmallow by hand. Simply hug, fluff, and rearrange the stuffing until it regains its original shape.
For an extra boost, try the dryer method. Put the Squishmallow in the dryer on a low or no-heat setting without a pillowcase. This is especially useful for larger Squishmallows.
If the Squishmallow is very deflated, you might need to restuff it. Open a seam, remove the old stuffing, and replace it with new material. This step requires some sewing skills.
By following these steps, you can re-fluff your Squishmallow and bring back its cuddly texture.
