    Knitted garments should be beautiful AND entertaining to knit!


    Curated, high-quality pattern library

    We offer a wide range of diverse, unique, and beautiful styles that we feel our knitting community will find interesting and entertaining to knit. Knitting a garment can take months, so trusting that you have a top quality, well written, and easily accessible pattern by your side makes all the difference during the journey.

    KnitFit only accepts patterns from designers if they have clear, concise, unambiguous directions, and all patterns are professionally edited and reviewed.

    Are you a designer looking for another place to put your patterns in front of knitters?

    Every pattern should come in all shapes and sizes:
    just like we do.

    The KnitFit Story

    The creator of KnitFit did not start out as a knitting-math magician...

    Jane didn’t even swatch for her first sweater (“It was intended for my husband. However, it fit Uncle Peter, who is 6’6”).

    Her creative and technical sides have always been
    separate, waiting to blend into a sole pursuit.

    Jane spent 20 years in the Computer Aided Engineering industry, keeping crafting compartmentalized from the tech side of her brain. But after a cross-country move, knitting became a way to connect with older women in her husband’s family.

    When a designer friend aided her deep dive into calculating modifications and mastering pattern-math, she began to see the power of blending creativity and technical thinking.

    In 2007, she opened an LYS: Needle in a Haystack.

    The many insights gained from running an LYS led to so many ideas. Customers spent weeks or months knitting sweaters in beloved yarns, often only to have them fit poorly.

    She realized then that knitting-math could be
    automated--in an app!

    Between her own tech background and her husband Dana’s, the skills were there to make it a reality. She began work on the KnitFit app, and suddenly more and more possibilities began to open up.

    She began adding features to allow it to be a place for all knitters to feel welcome. Jane’s dream is for KnitFit to allow knitters to get a perfect fit not just in the garments they knit.

    “For me, the biggest validation of the effort of creating KnitFit is when a
    knitter finishes a custom pattern and sees the results. They are
    universally excited about their sweater.”

    -JANE NICKERSON, Creator of KnitFit
