chalk lines
 

Will blue chalk lines come out of fabric when washed (on white fabric)?

I think it depends on the chalk and the fabric.

I have had lines made with the blue chalk in the Clover Chaco liner not come out and I have had the blue chalk from a pounce pad come out with no issues.

It depends on the fabric and also what type of chalk it is, there is wax and clay that I know of, one is harder to get out of certain fabrics than others. Its best to do a test on a small area and see

I tried blue once. Do not remember what brand. Had a very rough time getting it out. When I have to mark on white fabric now, I use a soft pencil.

Dilute the dark blue with baby powder or white chalk so t is not so dark, and check it.
Use cinnamon instead of blue chalk and check it.

I had a friend that had a bad experience with it.

Make sure you read the manufacturer's label for removal instructions! I have one marker that washes out with water but is made permanent by ironing. I have another that disappears with ironing. You don't want to mix those two up....

I've had problems with both the blue and the pink chalk. I mark lightly with a pencil now too.

I use only white chalk after a bad experience with blue chalk. Luckily it faded so only I could see it.

Try the Multi-Pastel chalk pencils in white and light grey. The dark gray works also. Made by General Pencil Co.
