The Trim-it Rulers by Lori Holt of Bee in my Bonnet are non-slip and easy to use for trimming up your blocks after piecing, applique or embroidery. Use the diagonal lines to easily center your block when trimming and use the colored outside 1/4-inch seam allowance marks to help you see what will show of your block after sewing it into your quilt. The ruler has aqua and denim markings printed in 1-inch grids marked in 1/8-inch and 1/4-inch increments. This package contains five square rulers. Sizes: 2.5x2.5 inch, 3.5x3.5 inch, 4.5x4.5 inch, 5.5x5.5 inch and 6.5x6.5 inch. Imported.
