Making Up >

  • To make up the sweater – first, stitch the letter of our choice onto the back piece using a coordinating colored yarn.
  • This is achieved by stitching over the V-shaped stitches you can see in the knitted fabric.
  • Then place the back piece and chest piece together with the right sides back to back.
  • After that stitch from the neck down on both sides for 8 inches.
  • Leave 7-inch leg holes then stitch again for 8 inches.
  • Weave in any loose ends, then prepare to make the sleeves.

Sleeves >

  • Make sure the sweater is inside out ->
  • With 10mm (US 15) circular needles, the hollyhocks yarn pick up and knit 30 sts around the leg hole.
  • Knit every row until the sleeve measures 3 inches from the picked-up stitch’s edge. Cast off.
  • Weave in all loose ends.
  • Repeat for the second leg hole.

The Harry Potter Font

Embroidered Letter >

  • For the embroidered letter, I looked at the Harry Potter font and sketched out my J.
  • I marked it out on the sweater with stitch markers as a guide, then began to stitch it with mustard yarn over the top of the V-shaped stitches.
  • Some of you knitters out there will probably be able to adjust the pattern to make the letter intarsia.

Harry Potter Quote

Mischief Managed!

“‘Right,’ said George briskly, ‘don’t forget to wipe it after you’ve used it –’

‘– or anyone can read it,’ Fred said warningly.

‘Just tap it again and say, “Mischief managed!” And it’ll go blank.’

‘So, young Harry,’ said Fred, in an uncanny impersonation of Percy, ‘mind you behave yourself.’

‘See you in Honeydukes,’ said George, winking.

They left the room, both smirking in a satisfied sort of way.”

— HARRY POTTER AND THE PRISONER OF AZKABAN BY J.K. ROWLING

Just like Fred and George Weasley, Jason is forever creating mischief and making us laugh.

  1. I made this for my bloodhound mastiff mix. She weighs 144 so I had to adjust the pattern. It’s a fun pattern. Now I’m working on her little brothers.
