Jen Chesnick form Say Chez! shares a tutorial at Therm O Web showing how you can make a curtain in just 15 minutes, with no sewing required. It’s a simple panel with a casing folded over from the top. She uses Peel n Stick Fabric Fuse tape to hold the casing in place and to hem the edges. If you wanted, you could choose to sew these seams instead. Go to Therm O Web to find her tutorial.
