I have the Bohin pencil which is like the Sew Fine. The only problem I have had is with the Graphite or Black lead. They did not wash out of the fabric.

Crashnquilt,

The instructions that came with mine emphasize that you should use the eraser that comes with it. They say it's the only way to get it off.

I sure like it. I used it to mark some bias binding this morning and it makes very easy to see lines. We're taking a class at the shop where I bought it, tomorrow. I just might have to purchase a different color to add to this one. Think I'll get a green one.
