    I LOVE this! It’s gorgeous!!!
    My husband’s niece is nuts over purple and I would love to make a quilt for her. How do you resize it to make an entire quilt? I’m thinking a large center block with smaller (larger than 12 inches) blocks on the corners. I’m not good at math (totally mathematically challenged), so figuring out how to resize is difficult. Queen or King size quilt.

    • Susie K Williams says

      Kathi, did you get the info you requested about resizing this for a Queen or King bed??? I just found this tutorial and am in love with this block But I’d really love to make a LARGE star in the center. Thanks for any help you can give me!! (You can email me at susieisnana (at)

      Hi Kathi! I regret to say, that I don’t have enough time (or quite enough details) to figure that out for you at the moment! I encourage you to get together with a math-minded quilty friend with some hot chocolate and graph paper to get you started :)

    Just wanted to say, that I really love this tutorial, it is very well laid out, and very easy to follow. I made this block yesterday, and now I am figuring how much material I will need to make enough blocks for a king size bed. My husband even likes this block, even though I used purple and white (he is simply black and white). Anyway I just wanted to say thank you again. I love this block.

    • Susie K Williams says

      Hi, Janice. I’d love to see a picture of your block(s)! I’m wanting to make this also for a King bed but I’d prefer a large center block rather than multiples of this one. Any idea how to figure out how to do the math for that??? (susieisnana (@)

    I’ve always wanted to try carpenters wheel, but this looks even better. Because it’s such an old design I’d love to sew it up in browns, greens and beiges. It has a lovely traditional look and is challenging enough to be interesting.

  4. Denise M says

    Oh, I absolutely love this block and what a detailed, complete tutorial. Is there anyway to compact it and print it for reference?

    I just have to try this!
