I use the white chalk also
Welcome to the Quilting Board!
I too use slivers of leftover bar soap. When I'm done, a damp washrag removes the markings.
The bar soap is one of my means of transfers, as are the wash-out pens from Wal-Mart. One end is Purple for using and it doesn't last long on the fabric. The Blue end stays until washed. Never had a problem with either.
Have a wonderful Quilting Day, make it your way!
This is what I use also. (white marking pen, FINE from Clover)
