estirar la ropa encogida

What it DID involve was a sink full of lukewarm water, a capful of baby shampoo and two large beach towels. That’s it!

Fill a sink with lukewarm water and add a capful of baby shampoo into the water. (Many tutorials I read said to use CONDITIONER…but this made more sense to me…so this is what I used.)

Let the item soak in the baby shampoo water and gently work it through. This will relax the fibers in the clothing.

Remove the garment from the shampoo water and gently squeeze it out. Do NOT rinse it.

Take a large towel and lay the clothing flat on it. Roll the towel up with the clothing inside it. Then, get another dry towel and put the piece of clothing out on the dry towel.

Gently stretch the clothing item as it lays out to dry. Continue to do this until the clothing item returns to its original size. Allow the item to air dry on the towel.
