Use a white piece of fabric dipped in hydrogen peroxide. Then dab at the scorch mark. Keep dabbing till it's all gone. Works every time. Don't ask me how I know this........

I've heard of both the white vinigar and borax, although, fortunately haven't had to try either. Appliquing a little mouse was my initial thought!

Scorched my sons brand new dress shirt cuff. Peroxide worked.

If tails don't appeal could appliqué a bow or make one from giant Rick rack with some of the bow loops partially sewn down to give Kitty something to play with-do the same on the kitty of the same fabric on the top row and it becomes a design element.

Many, many years ago when clothes had to be ironed, I would occasionally scorch something. I would immediately wash it and usually it came out. The secret is tomdomit immediately and not let the scorch set.

How about adding an applique in the shape of a mouse?

I don't see the mark either, but I do really like the idea of putting tails on to make it look purposeful. Sometimes these disappointments turn out to be happy accidents!

And now that you know your iron scorches, and you aren't sure with methods might remove a scorch, I'd say take some ugly light colored fabric and scorch it ,then test the suggestions. Sounds like a win-win-win to me. Happy cst quilt, ugly fabric used for a good cause, and something learned to tuck into your hat tricks of fixes.

Appliqué, appliqué, appliqué! :o

I think the only thing that removes scorch marks is a bleach of some kind. Marsha Kay suggested hydrogen peroxide. But like Bearisgray said the fabric is now damaged. Your quilt will wear through at that spot first. You aren't going to fix that. A sunburn heals, but not so with fabric. My best suggestion is to applique something over the scorched spot. You have a few cute ideas here. Good luck!
