As a long time sewer, I too prefer to use chalk, and sometimes use a thin soap bar.(As a new embroider, I also do something that is probably an embroidery no-no: I iron a fold line on fabrics that irons out when I iron on the stabilizer. However, the edges on the ironed fold lines remain beyond the stabilizer edges. --I always measure from the fabric edges for the center of the design placement so I know where it is, and make sure my folds go through it.-- I line up the remaining ironed folds with the grid marks on my hoops. I use a straight edge that is as long as the hoop is wide and long, to be sure they are aligned top to bottom and right to left, i.e., usually a meter stick most times. So far, this has worked for me, and the designs I have stitched have been centered. Then again, I do not have the numbers of stitchouts behind me that others here have, so my luck with this method/idea might be up soon!:>)
I realise this is an old post but see you are still having trouble, so,
I use tailor's chalk but I also have an old tenpin bowling scoring (white) pencil so I use that quite a lot on dark fabrics, it wears off long before the project is finished so has never caused me any problems.
I will often browse the charity (goodwill) stores here and look through old sewing collections, sewing boxes, etc. you never know what you are likely to find. Even vintage sewer's collections on Ebay will often turn up some better quality chalks than what you can purchase these days.

The one at JoAnn's. My daughter got me one. I think I use it Almost as much as my pins. Lovev it.
I vote for soap too. I have tried white quitling pencils and they break every time. Becky
I too use chalk.
Oh, I see this is an old post!! Didn't look at the date before I submitted my answer.
However; mops I am still having trouble. Just some weeks ago my water remover pen ink did not come out...OUCH ;D *2U
I use the end pieces of my bath soap(white), use your old rotary blades to sharpen and edge.
I use tailor's chalk, either in bar form or pencil form.
I use this chalk marker. It's one of my favorite tools. And the marks brush off with a toothbrush.
Try Transdoodle. It's mostly for quilting, but it comes in different colors.
You could pin a straight row on pins, or baste a row of stitches.
