I was hoping to really like this product a lot however, after the first use I was very discouraged. Because my day job I work with my hands I do not have the smoothest hands so every string seems to catch to every imperfection in my finger.
It's hard to line up and cut each pattern piece. It's easier to lay the interfacing down on a press and lay your pieces on top of it that way it doesn't shift around.
This product seems that it would be best for clothes rather than bags right now I'm currently only using it for pocket pieces.
