I love to make bunting for every holiday. It's because I don't really sew and this is SO easy. You just need bias tape for the top.. that's it. That's the secret. I've tried a lot ribbon and other things and that doesn't work. But, if you don't want to make a bunting. There are tons of them available on Etsy for under $30. This one from SewSweetViolet is a favorite.
Decoration for this party doesn't need to be elaborate. A bowl of pretty red apples would be fun.
