Whaaaat? I bet you are thinking, "Boring!"
Here me out.
I've used them, but let me tell you, I never knew there were this many different options for marking fabric.
Molly over at The Purl Bee has put together a fantastic collection of the different fabric markers out there, what they are used for and why they should be in your sewing essentials kit.
"Marking tools are one of the most useful pieces of a sewing kit, and there are so many different kinds! The marks they make can show you where to cut, where to fold or where to stitch. They can make a permanent or temporary line, and they're available in many different colors including yellow, blue, red, white and more. The secret to making your markers work for you is knowing which marker is the right one for your project. There is no such thing as the all-purpose perfect marker so it's important to familiarize yourself with the different uses of each kind. "
