Because t-shirt fabric is stretchy, it is really easy to make ruffles. You need to stretch the fabric out at the sides while pushing forward at the same time, This creates the perfect t-shirt fabric ruffles without having to mess around pulling threads.
I have decided I want to start sewing skirts. so easy and soooo much cheaper than buying them and you can get really nice fabrics. So here's to finally becoming my grandmother! (like the pleats in this, not as puffy as an elastic waist)
