In my country Uruguay nobody sells this kind of tape, so I have to order it online.
Sometimes I need really short pieces on my cosplays, and the sellers told me that you should use what you need, cut and throw away the rest of it. . . I don´t know you guys but for me it´s a pitty to throw this cool material!
I know its not as sturdy as how the seller sends it, but its something!
So i kind of stripped one piece and tried, and it worked! : ) Hope it helps!
