I have used blue washout marker in my quilts for years. And, all along, I've known that heat would permanently set that ink. And, I've been sooooo careful. I wouldn't even leave a quilt I had used washout marker on in the car, for fear the heat would set it, until the quilt had been thoroughly washed.
I was very careful.
But, this morning, I pulled a center off the Dresden Plate quilt, and it had been quilted through before. It was one of the centers that let me know I was going to have to pull the centers off the quilt and cut away the background fabric to get my stitches the size I wanted them to be. Anyway, I picked out the quilting, pulled off the center, and it was so wrinkled, I decided to iron it. I could not see the blue washout ink, but it was there. And, when it got hot, it came back.
It's very faint. You might have to blow up that pic to see it. But, it's there. And, now, it's never coming out.
Here is the block it came out of.
Fortunately, I have plenty of that fabric to cut a new center from.
So, there's today's lesson. Just because you can't see the danger, doesn't mean it won't come back when exposed to heat.
Seems very logical for summer. It's supposed to be 100* out today.
Everybody have a great Wednesday.
