The fabric pencil is my nemesis

I am going to cry. Really, I think I just might. I am working on a batch of dolls for a craft show in two weeks. I do the arms of the dolls in assembly line fashion - I trace them all out on my fabric and sew them all at once, then cut them out. I usually use a disappearing ink pen to trace my patterns ... well last night my pen ran out. So I used a water soluble pencil. I traced about 30 arms, sewed them up, and then tried to get the blue marks to come out. THEY WON'T COME OUT! My disappearing ink disappears in 12 hours, so I have never had to worry about them. But these stinking blue marks will not come out! I tried everything, spritzing them, putting them in the washer in cold water, drying them, washing them with soap ... nothing worked. The blue marks are still there. Which means that I cannot use the arms, since the seams have blue lines in them. Boo hoo hoooooo! I will have to go buy a new disappearing pen and re-sew the 30 arms. I have to re-do two hours of work! Waaaaaaaaaah!
