Perfect!
Exactly that I needed! I still think that you should measure before punching a hole, but it’s so much easier now!

    All the negative reviews are understandable only if you don’t understand how this thing works. No, pulling it apart and assuming everything is equi-distant is not realistic because it has moving parts and you are pulling with different tension, but each section is adjustable! Pull it as wide as needed then lay it down and adjust using a ruler, once all the points line up you can tape it with a strip of painters tape, flip and put the tape on the back. This locks the points in place. FOR THE PRICE it is awesome. A more expensive one might perform perfectly without needing to check against a ruler. This saves me a lot of time marking long borders or matching seam points on quilts I make. I love it!!!

    I purchased this for sewing as a button guide, pleating guide, etc. However, as a mixed media artist I have also used it for easily laying out art projects into thirds (rule of three) - no measuring needed! I have also used it to divide a canvas into equal segments (usually fifths), and again, no measuring needed. My husband is eyeing it for his leather work, and I am thinking it might work well in jewelry making to make sure an element is repeated at regular intervals when using unusual and irregular materials. Just super handy for creatives.

    I wish I had bought this sooner. This little tool makes positioning button holes so much easier. I make clothes for my daughter and most of the time her dresses requires button holes. I use to have to measure it but sometimes I'll be off by a few cm. This tool just makes the job easier and faster.

    For the price paid for this, it meets my expectations. I use it to divide a space into equal sections when I mark a quilt before quilting. No it's it's not very high tech, but a very handy device.

    Reviewed in France on December 10, 2024
    Je l’ai acheté pour mes travaux de couture. Plus besoin de me casser la tête pour mesurer les espaces entre boutonnières ou autres marquages. Très pratique, il n’y a qu’à poser le 1er repère au bon endroit et le reste se positionne tout seul. Je suis ravie de ce petit outil très pratique en couture mais pas que…. Très bien aussi pour marquer des repères en bricolage.
