Learn from my mistake...blue disappearing marker
I always use a blue marker that disappears with water to mark my quilts and have never had a problem until now, so learn from my mistake.
I marked what I thought was everything, sandwiched with 80/20 and a layer of 100% wool batting on top and then needed to mark one more line. Well..parts of that line will not come out. They disappear when I blot them with water, but show up again when it dries. I'm assuming that the pen soaked into the wool and keeps bleeding back onto the quilt top, which is white. This is a wallhanging and was not meant to be washed.
Not sure if this will only happen with wool or if it would have happened with just 80/20 as well.
Maybe this post will save someone else some trouble. Mark everything first!
