The New Hotness

  • Quilting Ruler: Dual Semicircles

    Along the same lines as the 45° triangle quilting ruler and the small arc quilting ruler, this one has a nonstandard 6-¼ inch diameter semicircle for the pattern Mary designed for a friend’s quilt:

    Semicircular Ruler - on quilt
    Semicircular Ruler – on quilt

    The 4-½ inch diameter semicircle is there because the larger half needed a handle for easier maneuvering. As with workshop clamps, quilters can never have enough rulers, so that curve will come in handy for something.

    Unfortunately, I did not mirror-image the layout like this:

    Semicircular Ruler - LightBurn layout
    Semicircular Ruler – LightBurn layout

    Which would make it correct when seen through the acrylic:

    Semicircular Ruler - engraving
    Semicircular Ruler – engraving

    Given the very specific use case, I begged forgiveness and was not compelled to get it right.

    The LightBurn SVG layout is a GitHub Gist.
