Hello and welcome to RU-vid sew family. TFS I too love iron on interfacing but I will not use it when I am creating with a thin fabric that is light if that makes sense. I tried it and you could see the interfacing that melted in between the fabric. I was pissed because it ruined my whole top. So, that's my take on it. Very nice dress for your mom. Praying you continue to grow on here you will do well. You're a natural.
Thank you for sharing. Please learn more sewing techniques. There are MANY good books and RU-vid tutorials on sewing. I myself taught many people how to sew. I love knowing how to show clear techniques and make it easier for my students. Keep up the good work and have a wonderful day 😊 Robin N Otis -Clayborne
