I like the Fabrico markers by Tushineko. They have dual tips (fine and large), are ink not paint, and last a long time. I used an Amazon gift card to get mine and store them horizontally.
But have also found some in quilt shops. They are perfect for filling in "mis-stitches" in embroidery and adding shading or changing fabric colors.
