of course you don’t need
that many scissors
But you should have 3 different scissors:
-Paper Shears with which you only cut paper
-Tailor Shears with which you only cut fabrics
-Embroidery Scissors or any other small and pointy for little cuts in thesewing process
Its really important, that you decide from the start, what you want to cut with which scissors, because if you cut paper as well as fabric the blades will get blunt very fast. You can see the ribbons I put on them? Everything with a black ribbon is only for fabrics, white ribbon means paper shears.
So if you want to, you can mark them, too, but be sure not to mix them.
All the best
