Add-A-Quarter 尺 1in x 6in

That little lip on the edge makes lining up the rotary cutter so much easier, especially for tricky foundation piecing angles. It’s a simple design but saves me from constantly guessing my seam allowance.

I was tired of eyeballing my seam allowances, but this ruler's built-in lip makes it foolproof for consistent ¼-inch cuts. It's been a game-changer for my foundation piecing projects, saving me time and fabric.

Finally, a ruler that actually stays put while I cut—that lip makes a huge difference for accurate quarter-inch seams. My foundation piecing has never been this precise or this fast.
