windows without curtain rods

So you can't hang curtain rods, or you can't sew? My favorite windows have all been created with thumb tacks and (unsewn) material. This material was $3 from Walmart

You can create amazing windows with scarves too! This scarf came from Claire's in the mall for $5

Rope lights can help you to create something different

also, certain Christmas ornaments can create a dazzling display

or you can buy beautiful expensive (worth it) curtains from Antrhropologie
