I made the mistake of leaving a magnetic needle minder on one of my projects a bit too long. I’m currently trying to remove the rust stain with milk (suggested by u/StitchLady40 seven months ago), because that’s all I have at home right now. Unfortunately, it looks like I need to escalate to something stronger.

The needle minder was the Hummingbird Enamel Needle Minder by Jessica Long Embroidery. All three of the needle minders I bought from that source use the same magnets and attachment style, so if you own any of them, definitely remove them from your fabrics ASAP.

(My WIP is the Air Mail March #1 Oriental Turtle Dove pattern from Lindy Stitches.)
