This is a great way to mark your lighter colored fabrics! It also shows up on dark as well as light so it’s a good choice for a busy print that has a lot of contrast especially if it has a lot of blues in it. We needed a third color because although it shows up on most fabric the blue shows up on, there are some that just work better with pink than blue (and vice-versa) It doesn’t iron off but you can brush it off or wash it off depending on the fabric.
