"Low Vertical Shank Quarter (1/4”) Inch Attachment Foot

There is the 'scant' 1/4 inch as you see in the photograph above... and then there is the exact 1/4 inch which the black metal guide helps to keep your seams perfectly in line and consistent throughout your entire project. You won't have to wonder anymore about whether your seams are accurate... and for me - relieves a bit of neck and eye strain because I have the assurance of stitching straight and perfect."

There are even additional uses for this foot, too. Be sure to scroll down the above page to see.

Hope this helps,
