I always like to experience new challenges! Making paper envelopes with a fabric-based program was a little different and of course a little difficult! It was not easy to make a fabric look like paper, unlike the simple appearance of the products! But on the other hand, I think that with all the challenges, the best program for such a product is Marvelous Designer! Because the softness and flexibility defined in this program helps a lot to make this product more natural.
