I am a quilt marker. I will premark an entire quilt, especially if the motif exceeds the size of my quilting space as is very common in wholecloth. My most favorite of all markling tools are the blue water soluble markers. For dark fabric I like my white ceramic mechanical pencil because the marks are very easy to remove for both products.
Motifs that repeat and need to be the same size, if I have not premarked I make a template from my final sketch or design source out of watercolor paper or card stock and trace around it with a water soluble blue pen as I go. Border motifs, I will photograph or sketch so I have it available to me by the time I get to the bottom bit. I am also big for marking registration dots, especially when doing ruler work. 90% of all client quilts that hit my frame have a minimum of 2 to 5 hours at the "drawing board". I do a lot of sketching before I start quilting and that sketch pad is up in my LA studio with me when I start quilting so I can refer to it.
