Certainly, the best way is to actually use your products, although, laying them out flat in the sun for about an hour or so, will do the trick!
When products are folded they will naturally develop crease lines. These will soften over time.
We also recommend using a hand steamer on the back of the mat to get stubborn wrinkles out. Do not iron. The more you use your products, the more the vegan leather will soften and form its natural shape.
