You can select items in 2 ways :
The minimum quantity you can order is only 20 cm ( fabrics or ribbons).
It is not always necessary to have ""round"" quantities. At Stragier you can choose the exact length you need
If 2,15m is enough you don't need to buy neither 3m nor 2,5m.
You enter 2,15 as a quantity and off we go !
