I try to reduce waste as much as possible. I try not to buy any newly produced fabrics/materials but solely from deadstock. I also use discarded clothing as fabrics whenever it seems fit, such as old Jersey T-shirts, leather biker jackets, lingerie and parts of corsets.
Also I find it important to only buy quality fabrics that, if taken care of, will survive the test of time. Once I will start selling I will only offer made to order, so that there will not be any overproduction. I love this method, because impulse buying doesn't exist this way.
