I have a variety of marking tools and use different ones on individual projects. It is Very Important that you Test your choice to make sure it will come out Every Time, Each new project. Some come out easily one time then don't on the next project. Always read the packaging for removal instructions. You don't want to heat set, cause a marker to become permanent because you ironed over it, or added water when a brush or eraser was all that was needed. I use chalk often. I do like the air/water removable markers but they disappear on their own within a few hours so those I use when marking small areas, quilting then marking next area. I've always had good luck with a good sharp pencil, though I've read comments from people who had problems. In 45+ years of sewing a pencil remains my first choice for marking but sometimes doesn't show up or sometimes I want a heavier mark. What ever you choose to try TEST removal FIRST

I use a regular #2 mechanical pencil for marking on light fabrics and the equivalent Bohin mechanical pencil with white chalk/lead for marking on dark fabrics. I've tried any number of methods over the years and these are the only ones I now use. Only had an issue once with the regular lead pencil but I think I was probably a bit heavy-handed that time as well as changing my mind on the quilting design so it was pretty obvious. But 'scrubbing' with some liquid dish soap and a soft toothbrush, it eventually came out as well. I, too, mark as I go now as most times the marks will wear off after time. And we all know how long it normally takes to get something hand quilted!

I use a frixion pen

I have used a light lead pencil. Right after stitching that area, lightly erase it or take a small artist's paint brush to it. I've seen on one video, a handquilter just uses her needle to lightly sketch (indent) as she goes. All depends on your design.

This is about what I do, too. The only thing is to not be too heavy-handed with the lead pencil.

I am totally mistrusting of ANYTHING that is inky or liquid based.

I prefer chalk on darker fabrics.

Where do you get Dove soap for free? Just teasing, LOL, couldn't resist!

This is really beautiful!

I like the blue water soluble pencil for marking lighter fabrics and the chalk that comes in a mechanical pencil (Bohn) for dark fabrics. I've never had the blue not wash out even with a light spritz of water and blot with a wash cloth. You do have to be careful you don't iron it while it is visible however as it will heat set the blue marks. I've never done that but heard it from others.

I have used Fixon pens as well with success. You have to be careful of the red on some fabrics as it will leave like a faint bleach line. I've never had problems with them washing out or reappearing.

Agree that you should always test your marking method with the fabric you're using to make sure it will come out.

I'm wondering, for those of you who use chalk, how do you sharpen it? I can't find a sharpener my chalk will fit into.
