This handy 6" x 1" ruler and stitch gauge is a must-have tool for stitchers. Not only is it magnetic, but it has a great stitch gauge measurement that suggests your strands of floss and needle size for thread counts of 10 through 40 count fabric! Not only that, but you can easily tell what count of fabric you're working on using its fabric count gauge - no more guessing what count that project was on anymore! An excellent tool and resource for any needleworker!
