My husband does not enjoy dressing up. I, on the other hand, love dressing up. So each Halloween, it’s a struggle to find a costume that is  “dressing-up”, but in fact, is not really dressing up. This year is a total win, I just ordered two Gryffindor scarves off Ebay, and will be purchasing two sets of ear muffs the next time I see them in a store.

If you are not familiar with the Harry Potter scene from The Chamber Of Secrets, the characters must harvest baby mandrakes and make a draught to cure petrification, which happens when you accidentally see the reflection of a basilisk. You must wear ear muffs to protect your ears from the mandrake screams (they scream when pulled up from the dirt), which causes unconsciousness with baby mandrakes, and death with full-grown mandrakes.

Very scientific.

I also created a printable mandrake label {Get a small mirrored one here and the regular one here}. You can put in on a onesie like I did (with iron-on transfer paper), or you can print it and put it on a box or pot, however you decide to style the costume.

Stuff each stem with polyfil. Using the tail, sew the stems on the top of the hat. Sew them a bit forward on the hat, and not perfectly centered on the first round. 
Sew on the the leaves in any manner that works for you. Sew the base of the leaves to the stem. To keep the stems upright, baste stitch the leaves together with a few strategically places stitches. This keeps the hat and roots upright and sturdy.

  1. Hi! I found this pattern and I really loved it especially since my aunt LOVES Harry Potter, I am making it for my baby cousin. I am pretty new to crocheting, and in your video tutorial on how to do the hdc, it was only in chain stitches and I was wondering how you do it in a regular round- Do you just go through the whole stitch or just the front loop? Thanks!

    1. Hi Gracie! It depends on the pattern, but normally you will work through both loops on top. For the mandrake pattern, you will work through both loops! Please let me know if I can help with anything else!

  2. I cannot for the life of me make the leaf pattern look like leaves :(
    I tried turning the piece between step one and two and it just came out like a rectangle and I tried going in a round and I just got a half circle
    Can you maybe provide some additional details? I’m not really sure how they are supposed to come out from the photos

    1. Hm, this is interesting! You are working it in the round, are you working across the other side of the chain? The chain should be down the middle, like the middle vein on a leaf.

  3. I tried printing the label on transfer paper and it won’t print clearly. Do you think it’s the paper? I’ve never used transfer paper before.

  4. I know this has been awhile since this pattern was submitted, but I’m having trouble with the leaves. Would someone mind posting a close up picture of their leaves??

      1. Do I sew two leaves together to make one leaf? I followed the pattern and it doesn’t look like a complete leaf- if that makes sense.

          1. I think I got it- it didn’t say if I was supposed to keep going in a round or if I turn for round two. When I went in the round it looked better

  5. To modify for newborn size, would I use a smaller hook and reduce by a couple of stitches in each section of the instructions? Any other suggestions? My daughter has requested these for newborn photos of her twins :)

    1. Hello!
      The trick to perfectly sized hats is the circumference! You will want to make a circle with a circumference of about 12″. To find the circumference of your circle, you will take the diameter and multiple it by PI.
      I hope this helps!

    2. Melissa, how did using a smaller hook and reducing stitches work out for you? I am just starting this for project for myself. My baby will be very fresh for halloween!!

      1. I just made one sized down for an infant. I used the same size hook, but only followed the pattern to Row 5 (40 stitches), then I added 7 additional rows for a total of 12 and it measured very close to the other newborn hats I’ve done.

  6. I would love to make one of these for my friend who is due a baby in September, she just adores all things Harry Potter. How much of the Almond colour is required?

  7. Aww…this is such a cute hat. Do you have a panda pattern btw? My daughters love panda, and I’m thinking to make a crocheted hat pattern for her.

  8. When I first saw the link, I thought “WHY would anyone make a mandrake hat for a baby?” Historically, mandrakes were thought to be an aphrodisiac! But ok, a baby mandrake and the two of you wearing earmuffs – that’s cute. :)
