Knitted Water Bottle Cozy and Carrier Pattern

A water bottle cozy carrier

Sarah E. White

We all know that it's best not to use bottled water because of the resource-intensive nature of plastic production and because so few bottles ever get recycled. This water bottle cozy should make it easier to break the habit so you can tote around your metal water bottle throughout your day.

The pattern is quite easy and is worked on double-pointed needles. It is finished off with a handmade I-cord so you can easily hang onto it or strap it to a bag.

Materials Needed

  • Approximately 50 yards Caron Simply Soft Eco, or medium weight acrylic or an acrylic blend of your choice
  • Set of 4 size 8 US double-pointed knitting needles
  • Scissors
  • Yarn needle
  • I-cord maker (optional)

Pattern Gauge and Size

Gauge: About 17 stitches and 18 rows per 4 inches in Turkish Stitch in the round, unstretched. Gauge is not critical and the finished project will stretch considerably.

Size: About 9 inches tall and 5 inches around unstretched. This fits an average size metal water bottle. The size can easily be altered by knitting more or fewer rows in the base or the body of the pattern.

Water Bottle Cozy Pattern Instructions

You will find that this bottle cozy pattern is a nice introduction to working with double-pointed needles. They do take a bit of getting used to because you're working with four needles at once. There is very little shaping to this project, so it's a great beginner's piece that will set you up to knit socks and other small projects in the round.

  1. Cast on 9 stitches. Divide onto 3 needles, join in the round and knit 1 round.
  2. Knit in the front and back of each stitch, 18 stitches.
  3. Knit 3 rounds.
  4. Knit in the front and back of each stitch, 36 stitches.
  5. Knit 4 rounds.
  6. Knit 1, *yarn over, knit 2 together. Repeat from * around, ending knit 1.
  7. Repeat this round until piece measures 5 inches or an inch or so shorter than your bottle. The cozy will stretch when carried with the strap.
  8. Using an I-cord maker or working by hand, make an I-cord about 30 inches long, or the length of your choice.
  9. Sew the strap to the inside top of the carrier. Insert your bottle and drink happily.

Choose an Eco-Friendly Yarn

Originally, this simple pattern was designed to use Caron Simply Soft Eco, a yarn that was made in part with recycled plastic bottles. It is a fantastic concept and, unfortunately, the yarn has since been discontinued. 

Blending recycled plastic into fibers, we can knit with is something that a few environmentally conscious yarn companies have and continue to play with. Most of the yarns to date have not had a long life. However, as consumer demand increases for sustainable and recycled textiles, we can only assume that this is not the last we've heard of PET (polyethylene terephthalate) plastics in yarn.

To keep in the spirit of the eco-friendly nature of this water bottle cozy yarn, do your best to seek out other recycled or sustainable yarns. Many fiber blends are now available from recycled materials. Natural fiber choices like hemp are a great choice as well. In the case of hemp, your bottle cozy is likely to last as long as the bottle.
