I use a yellow quilting pencil. That's the only thing I've ever used and not too pleased with it. Firstly, I find it extremely difficult to mark with a stencil as it can't be clearly seen and the colour comes off pretty easily. Secondly, I can't find a perfect sharpener to sharpen it. And lastly, it doesn't come off completely after I wash it after quilting.
Does anyone have advice on how I shd use this pencil to mark my quilt? Any suggestions for a good sharpener?
