Cecile has allowed me to reprint her pattern and photos in this post. Her designs are beautiful and shows how plastic trash can truly be transformed into treasures. While she doesn’t give all the details for creating the special designs shown in the photos, her beautiful creations do provide us with numerous ideas for crocheting our own unique designs with recycled plastic bags.

Recycled Plastic Water Bottle Carrier Pattern By Cecile Chi

Directions for a carrier for a half-liter water bottle:
Cut strips across the bag, 5/8 to ¾ inches wide to create your plarn (plastic bag yarn)

Beginning the carrier
Begin by making the base, a flat circle with one end of the “yarn”, make a slip knot loop
Use size F and G crochet hooks as directed
Ch 3

Round 1
2 sc in each of the 3 ch
2 sc in sl st
2 sc in ch 1 (10 stitches)

Round 2
8 (2sc in next sc) (18 stitches)

Round 3
10 (2 sc in next sc, 1 sc in next sc) (28 stitches)

Round 4
8 (2 sc in next sc, 1 sc in next sc, 1 sc in next sc) (36 stitches)

This completes the base.
Continue sc in each sc until the carrier is about 6 inches tall (about 22-24 rows).

Change to size G crochet hook.
Ch 180 (for a 36 inch handle), attach to the opposite side of the carrier.
Change back to size F crochet hook.
Sl st in each ch, attach to the beginning of the handle
Sl st on the other side of each ch, fasten off.

Directions for a carrier for a 20-ounce sports drink bottle:
Follow the above directions except keep increasing around the base until there are 40 stitches instead of 36. […]

I just recently completed this water bottle carrier or holder. It’s another item off my to-do list. This carrier holds a 1 liter bottle of water. I crocheted a wider and longer strap so this may be worn as a sling bag over your shoulder and across your body. The strap is 40 inches long so you have a nice comfortable length to carry this bottle. I found this worked well as this 1 liter bottle is a bit heavy when full. Also because the bag is crocheted using recycled plastic bags, you don’t have to worry about it getting wet from the condensation from the cold bottle. Don’t know how to make plastic bag yarn? — here is the tutorial link.

Here is the free pattern that I share with all my readers. Take care and blessings to all.
