I have been a bit wary of using blue washout marking pens ever since a disaster I had a few decades ago. When they work and wash out, they are amazingly useful tools. Kelly Cline uses them and reading her info has encouraged me to give them another chance in recent years. This is the brand she recommends. You can find them on Amazon.
I had been using my Hera marker on this vintage top, but marking like that isn’t easy to do while traveling. So I went for the blue, figuring if it didn’t wash out, it wouldn’t show much either. I use this to remove marks as I go.
I got my bottle from Hab and Dash. I’m sure you can find it in a Google search. It comes with a spray top, but I don’t use that. I love this little invention.
This is made by Dritz. It is a felt tip marker that you can fill with water for removing the blue pen marks. I fill it with the Blue Line Eraser shown above.
I don’t waste any from overspray and my quilt doesn’t get soaked. When I’m done, I will run this quilt through the washer without detergent to thoroughly remove anything left in.
As always, your mileage may vary, but so far (fingers crossed) it is working for me.
Have a great day!

looking hard for that green water pen of yours….I cannot find it…
Can you provide a link for the Dritz marker, or tell me what it is called? I have not been able to find it anywhere and it looks very handy. Thanks!
That sounds like exactly what I need! I had a significant “miss” with a blue marker the last time I tried one – spent more time trying to scrub the marker out than I spent making and quilting the quilt.
Such a cute top. Thanks for the tips – I’m looking for something like that. I’ve really been wanting to try using a Baptist Fan stencil I have but I can’t figure out how to position it to mark. I know you marked the edge, but I want to quilt it all over. I’ll keep working on it!
Please share more info on the Dritz pen. Have you had it a long time? Cannot find anything like it on the internet. Thanks.
Thanks Katy! I always enjoy reading your posts.
