I saw this on Pinterest (with no link to the actual source) and I am so freaking in love with it that it's ridiculous. Has anyone seen something like this or any tips for making it? I can sew. (I'm a beginner but it really won't be that hard. It's just tulle with an elastic band on back as it looks like it doesn't stretch all the way around.)
Thanks all!
