This is a Waving Rainbow Flag with Lesbian Symbol Woven Patch. It's a great way to wear the Traditional Rainbow Pride flag! This woven patch measures 12.5cm x 5.5cm in size.
You can simply use your iron at home to attach it to cotton clothing or a suitable backpack. We recommend using an old t-shirt or a tea towel over the patch and iron it until you can see it's properly affixed.
