Comments

  1. This is a basic hat pattern. Could use the magic circular instead of short circular and switching to double points. Select any yarn that is very soft, washable, at least hand washable, but in same yarn weight. If using different weight yarn must make adjustments. Head sizes do differ so a swatch is a good idea, measure, adjust for size required.

    I am a new beginner at knitting. I prefer using the straight needles. Have not yet tried the circular needles. Is it possible to knit this hat with straight needles.

  3. This project needs a picture.

    • I agree. If I decide to wear a chemo hat I’d like to know what it looks like. Especially with chinchilla yarn. Is this a faux fur- type yarn?

  4. Trying this today as it starts to get chilly here. I’m trying to find out if the terms are US or UK so I cn convert to Australian, oh well I think I have it sorted. Will see. Please remember you have an international audience.

  5. when do you switch to the double pointed needles.

  6. I would like to see a picture.Is that possible?

  7. I would like to see a picture of the hat? Is it for adults or children? I am interested in patterns for Children size chemo hats.

  8. Am I missing it, or is there a picture of this project???

  9. I’m a beginner knitter, I will try my best to make this hat. Thanks for the pattern!
