Catherine Holbrook on Instagram: "The mental gymnastics I have to do to wrap my mind around how this works 🤯🤯 One of the coolest tricks I’ve learned recently! This makes installing elastic into a waistband super easy, because you don’t have to insert it after the waistband is attached. You insert it FIRST, and it’s sewn into the waistband. Then attached. It prevents the elastic from shifting around within the waistband! So flipping cool! . #sewing #sewingtricks #sewingtips #tipsandtricks #lifehack"
