    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.

  2. 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?

  3. 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.

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

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

  6. 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.

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

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