Perfect Piecing Seam Guide
The Perfect Piecing Seam Guide, designed by Celine Perkins of Perkins Dry Goods, allows you to mark your sewing machine with a perfect scant 1/4 in. seam for perfect piecing every time! Great for use when you don't have a 1/4 in. piecing foot available; you can even use it to check the accuracy of your 1/4 i.n foot.
