I have posted this before but this is my favourite for dark fabrics. If brushes off with a dry toothbrush if you mark lightly or a damp cloth. [ATTACH=CONFIG]572072[/ATTACH]​only use white chalk as coloured chalk can stain.

I like tailors chalk. It comes in several colors, shows up well, and comes off with heat.

The ceramic pencils are the best for marking accurately. I have a BOHN (France) pencil. It works like an eversharp and you can buy different colored leads for it. I just made a pile of Boston Blocks and used it on black with white lead. I needed the line to be exactly in the right spot, or the blocks might turn out wonky.

The leads are very expensive, but once you have paid for it, you will have enough for life and more. You could share leads with friends, also.

I just don't think a soap sliver would be consistently sharp enough.

I have a Dritz chalk marking pencil (advances much like the Clicker Mechanical Pencils. It came with 8 sticks of white chalk and several pieces of different colored chalk. I find that it stays on very well. It also came with a sharpener so that your chalk can be sharpened to a long sharp tip if needed. I like it because it's very easy to control. Of course, wouldn't you know that the refill for it isn't available in the store (JoAnn's) but can be ordered through an office supply site.

Popover, is the Clover pen you recommend the iron-off or water soluble version? Thanks

I love using the Clover white marking pen. It washes out and it does stay on until you want to remove it.

Tartan- the point breaks off my chalk very easily when I am marking w/a stencil, do you find that happening or do I just have cheap chalk?

Jeanette- be careful of the colored chalk in that set. I have used the pink and yellow and had difficulty getting it to wash out.

I like Roxanne's pencils. There is a white one for dark fabrics and a silver one for light fabrics. I also use the Clover chalk in the applicator with the tiny wheel. It makes a very thin line of chalk. Neither of these products has chemicals which may deteriorate the fabric over time. Sometimes on light fabrics I also use a mechanical pencil made for fabrics called The Ultimate Marking Pencil.
