Have you ever used Clover water soluble pencils? I used them for the very first time marking this quilt, and I think I spent more time sharpening the pencils than I did marking the lines. The lead kept breaking below the shaved area. See the blue bit of lead in the upper left side of the bowl? There are countless more, of both the blue and pink variety, buried under those shavings.
Even with a light hand and barely sharpened point, the lead kept breaking and popping out. The pink pencil was worse than the blue. I marked 40 lines with each pencil and here's what the pencils looked like when I had finished:
On the bright side, I've finished marking the quilt top and can now move on to basting. Did I mention that at 68" x 76", this quilt is the largest I've made? I'll be spending the better part of the day on the floor pin basting. Guess that's not such a bright side after all.
