QUILTING RULER FOR CURVES
NEO CURVES RULER
Cut perfect quarter, half and full circles, from 1" to 24", with one single ruler. Convex and concave pieces that fit together smoothly, without bulges or puckers.

Convex & Concave
Cut both pieces of every curve with perfect alignment, so they sew together into flawlessly smooth curves.
Quarter, Half & Full
Quarter circles from 1" to 12" in ½" increments. Half and full circles from 2" to 24" in 1" increments.
Finished Sizes
Every slot is marked with the finished size in inches. Seam allowances are already included: ¼" on the curves and 0", ¼" or ½" on the edges.
Non-Slip Backing
The bottom surface grips the fabric and keeps the ruler stable, for precise cuts and added safety while you work.

How it works
Check
Look up the fabric you need for each piece of the block.
Align
Place the ruler on the fabric using the guides for convex or concave pieces.
Cut
Slide the rotary cutter along the slot of the finished size you want.

¼" or ½" on the edges: you choose
The curves always include a ¼" seam allowance. On the straight edges you pick the allowance, depending on what the pattern needs or on how confident you feel sewing curves.
¼" edges
The block comes out at its exact size, with no need to square it up. Ideal when you already sew curves with confidence.
½" edges
You get extra fabric to square up the block after sewing: trim ¼" past the seam, then to the finished block size plus ½" (e.g. FB 4" x 4" → 4½" x 4½"). Ideal if you are new to curves or the pattern asks for it.
Then sew the curve
Place the two pieces right sides together, align the curved edges, sew with a ¼" seam allowance and press. Use your favorite method for sewing curves.

What can you sew with it?
Three basic shapes, in dozens of sizes, are the start of countless curved blocks: drunkard's path, circles, arches, petals, waves and modern designs of your own.
Quarter circles
1" to 12"
Half circles
2" to 24"
Full circles
2" to 24"
More curved blocks and patterns are on their way. Ruler owners get them first.

Frequently asked questions
Can I use it if I am left-handed?
Yes. For left-handed use, rotate the ruler 90 degrees counterclockwise and cut along the same slots.
Which rotary cutter do I need?
All curves can be cut with a 45 mm rotary cutter, though the smaller curves may be easier with a 28 mm cutter.
Are the sizes finished or unfinished?
The numbers on the ruler are finished sizes, in inches. The seam allowances are already added, so you just choose the size you want in your quilt.
What is it made of?
Shatterproof ⅛" PETG, for precise curves and durability. It is manufactured in the USA by Quilter's Rule® using Fabric Gripping Action®. Keep away from heat (irons, hot cars) and store flat.
