How to Use the Quilters Select 6.5" x 6.5" Non-Slip Ruler: Tips for Squaring Small Blocks

What Is the Quilters Select 6.5" x 6.5" Non-Slip Ruler?

The Quilters Select 6.5" x 6.5" Non-Slip Ruler is a small square ruler for marking, measuring, and cutting fabric with accuracy. Its compact square shape is sized to sit neatly over smaller pieces and blocks, so you can check, trim, and square them without a larger ruler overhanging your work.

It has clear, easy-to-read markings, including 1/8-inch, 1/4-inch, 1/2-inch, 3/4-inch, and 1-inch measurements, as well as multiple angles for precise marking and measuring. A unique non-slip coating helps keep fabric in place for clean, accurate cuts, and the coating is designed to last even if the edges show wear. The one-inch perimeter lines feature a dual-number system that reads left to right and right to left, and its exact perimeter measurement is designed for precision when squaring blocks. Quilters Select rulers are available in multiple sizes, and this design is made for both right-handed and left-handed users.

Why Quilters and Sewists Use It

Small pieces leave little room for error. If a block is cut slightly off size or out of square, seams become harder to match, and those differences add up across a quilt top. A dedicated 6.5-inch square lets you check the size in one placement and correct it before you sew.

Quilters reach for this size for squaring small blocks, trimming pieced units, and measuring pieces before cutting a full set. Sewists use it for smaller pattern pieces and craft sewing, where working from either direction saves time and confusion.

How to Use It, Step by Step

  1. Start flat. Press your fabric or block and lay it flat on your cutting mat, smoothing out any fold or wrinkle underneath.
  2. Place the ruler. Set the 6.5-inch square over the piece so it covers the area you want to measure or trim, and let the non-slip coating settle onto the fabric.
  3. Align to the perimeter. Line up the one-inch perimeter lines with the edges of your block or fabric. Use the numbers that read upright from your side — the dual-number system works left to right and right to left.
  4. Check size and angles. Read the 1/8-inch through 1-inch markings to confirm the piece measures what your pattern calls for, and use the angle markings when a cut or corner needs checking.
  5. Hold and cut. Spread your hand flat across the ruler, fingers well away from the cutting edge, and run your rotary cutter smoothly along the ruler edge.
  6. Turn and repeat. Rotate the block, align again from a freshly trimmed edge, and trim the remaining sides. Measure the finished piece once more before cutting the rest of the set.

Practical Tips

Work from the numbers facing you. The ambidextrous numbering means you never have to lose your place or count backwards — pick the set that is upright from where you stand and trust it.

Trim a little at a time when squaring. Align, take a light trim, then turn and realign. That helps you reach the exact size without cutting away more than you intended.

Press the ruler down evenly, not just at one corner, so the coating can grip across the whole surface. If the fabric shifts, stop and realign rather than steering back mid-cut.

Care and Storage

Store the ruler flat or hanging with its edges protected. Wipe it with a soft cloth to remove lint and dust so the markings stay easy to read. Keep it away from prolonged heat and direct sunlight, and check the edges before a big session — a damaged edge can steer a blade off line.

Project Ideas

Use this ruler to square up small pieced blocks before joining them into rows, trim small units to a consistent finished size, and check measurements as you go. It is also handy for mini quilts, table runners, mug rugs, and other small projects where precision matters more than ruler size.
