Step 1. Fill your sink with warm water
Step 2. Add some shampoo (about the size of a coin) and stir the solution

Step 4. Leave to soak for 30 minutes
Step 5. Take out the item and rinse with water
Step 6. Stretch the coat in small patches
Keep your hands close to each other, gradually moving to other areas, until you have covered the entire surface of the fabric.
Step 7. Stretch the product again, increasing the distance between the palms by about 30 cm

Hang it so that the weight of the garment continues to stretch the desired area of the fabric (i.e., if the sweater has sat upright, hang it by the shoulders).
