Here is a picture show on one of my latest DIY's. The children's room is like an echo chamber because there is nothing hanging on the walls. There is no curtain pole over the window, so while figuring out how to attach one to the stone wall so I can hang some fabric I try create something else to swallow noise.
Fold twice before pinning the fabric to the frame.
Pin the fabric in this order to get an even stretch to the fabric.
The fabric is one of my favourite thrifted bed sheets. Lots of fabric enough for lots of DIY projects! Me likes!
