  • Women’s sweatshirt pattern (S – XL) in PDF format
  • 1.60 m of Recycled Brushed Jersey fabric
  • 30-mm elastic (The pattern instructions include guidance for each size)



  • It’s important to wash and iron your fabrics before starting to work with them.
  • Cut all the pieces in the same direction as the grainline to avoid color changes in the fabric.
  • To sew this fabric, we recommend using a jersey ballpoint needle, size 80/12.
  • If you don’t have an overlock and your sewing machine doesn’t include elastic stitch, you can sew using a zigzag stitch with a loose tension on the top thread and a small stitch size, so that the stitching doesn’t break when we pull the seams.
  • Also, avoid pulling the fabric while sewing so that the seams don’t stretch out.

Step-by-step instructions to make the turtleneck sweatshirt

To make this sweatshirt, first you need to download and piece together the PDF pattern. Read all the instructions carefully.
