These are so simple, but such a good tool for threading needles. I cross stitch, and depending on the fabric I'm using or the count/inch of the fabric, the needle size that should be used varies greatly. These threaders can accommodate nearly every needle size that I use with my stitching with its larger end or with its smaller end. The only size needle that forces me to have a different threader is the size 28. For that size needle eye I use another type of threader. This threader can be used with a size 28 needle, but it's a very frustrating experience for me. I can definitely recommend this needle threader, especially when you can buy 10 of them at once.
