I use the Sewline fabric pencils. The leads are very fine and come in a range of colours. I have two, a pink and a blue one. They have erasers on the top and both the erasers and the leads are available in refill packs. I've never used the eraser as the lines are so fine and easily covered by the stitching. I've never had a problem with the lines showing.

my favorite is the Clover pencil with different colors of lead

Yes, I have used the soap method for many years on alterations - but will keep checking on this thread for hints on lighter fabric. I have used #2 pencil but sometimes have a heavy hand.

i love the idea of a sliver of soap!!! I absolutely never thought of that!!! Is Dove because that's what's in your house or for another reason??

Now that you guys got me started, 2 questions, one are the washable markers just the markers you see in the stores that anyone can buy, and other questions, where and what are the gels. I have a couple of markers to use for hand quilting but am not happy with them, would love to go to something else. And Oh yah third question, does everyone starch heavy before you start quilting? I usually don't so I don't have a lot of starch in my fabric before I start.

I use the clover white marking pen (fine) for dark fabric (it can be ironed out or washed out) and the blue fine line water erasable marking pen for light fabrics by dritz. I use them most along the edge s of fabrics that blend together so I can see where to satin stitch.

The best marker that I have found is the Sewline ceramic pencil. They are not cheap (for me) but well worth it. There are other ceramic pencils that have hard leads but Sewline is great. Just google it.

My DH says to try soapstone from a welding supply store. Or Silver Streak used to mark on Stainless.You can get these at a welding supply also. It washes off ,does not heat set.He is a Union Pipefitter and has used these products for years. Contact a local supplier .

These are the ones I was recommending earlier on!

I want something with a very thin line; most markers are too fat. I, too, am interested in learning more about the gel pens. I am assuming they wash right out. Any special brand---are they are JoAnn's----are they made especially for sewing?????
