Mine is actually a big eyebrow pencil sharpener but the chalk will fit in a regular school sharpener if it has the regular pencil hole and the big red pencil hole. It takes a bit to get it going in the sharpener but once you have it started, it goes quite easy. Check out the back to school supplies at Walmart. I only use WHITE chalk as coloured chalk can stain a quilt top.

Thanks Tartan. I will definitely check out the sharpeners. What a wonderful, generous forum we have!

The problem with colored chalk (including tailor's chalk) is that the colors may permanently stain fabric, especially whites. They don't always wash out and the chalk does not come with any guarantees. Tailors chalk is most often concealed in seam allowances; quilting lines are highly visible. White is the safest.

I had a problem with the green Crayola marker not washing out. Plus the item has to be washed before use or gifting. I use soap, chalk, or (my favorite) the air erasable Trace n Mark by Nancy Zieman.
