Corner Pop Ruler

Corner Pop® Tool – Studio 180 Design

Say goodbye to waste and frustration—Corner Pop® makes adding perfect fabric corners fast, easy, and precise.

Traditional corner techniques often mean drawing lines, sewing on the bias, and crossing your fingers for a straight result. The Corner Pop tool changes all that. Instead of marking and hoping, you’ll trim first, add an oversized triangle, and square it up for flawless results—every time.

With 24 sizing options in quarter-inch increments, this tool is ideal for upgrading basic units or adding creative flair to your quilt blocks. Whether you’re making small accents or bold design statements, Corner Pop gives quilters of all levels the freedom to get it right without the stress.
