About This Granny Square Pocket Bottle Holder Pattern
This pattern makes a snug mesh bottle holder with a solid crocheted base and the option of a granny square phone pocket. It includes two strap methods so you can choose the level of stretch and stability you prefer. The design is easy to adapt for different bottle sizes by increasing rows.
Includes step-by-step instructions for the circular base, mesh body, strap options and two pocket styles. Suitable for using DK cotton yarn with a tight gauge to ensure a snug fit.
Why You'll Love This Granny Square Pocket Bottle Holder Pattern
I absolutely love this pattern because it combines plain functional crochet with a playful granny square pocket to keep your phone handy. I enjoy how quickly the circular base grows into a neat cylinder and how customizable the mesh body is with colours and rows. The two strap options mean I can make a stretchy everyday version or a firmer horizontal handle depending on what I need. It is satisfying to make and practical to use — I took my first sample to a festival and it held my water bottle and phone perfectly.
Switch Things Up
I love changing colours every few rounds to create bright stripes — try a rainbow granny square for a pop of colour.
I often swap the DK cotton for a slightly thicker cotton and a bigger hook to make a chunkier holder for insulated bottles.
I sometimes add a small lining inside the pocket or sew on a metal snap to keep the phone secure.
I also experiment with strap length: shorter for a shoulder bag, longer (240 ch) for a crossbody festival strap.
I reinforce the underside of the strap by sewing ribbon or fabric to prevent the cotton from stretching over time.
If you want a keyring version, make the base smaller and use thinner yarn to create a mini bottle cozy.
I like to embroider initials on the granny square to personalise gifts — simple chain stitch works well.
Try combining mesh and solid panels for a two-tone look, switching yarns every 2–4 rows.
I sometimes make a drawstring with a contrasting colour and add wooden beads to the ends for a boho finish.
If you want a sturdier strap, crochet it in HDC horizontally as described and topstitch it down tightly for minimal stretch.
Common Mistakes & How to Fix Them
✗ Working with a yarn that stretches too much will make the holder loose over time; choose a sturdy DK cotton or reduce hook size to keep the mesh snug.
✗ Not checking gauge after the increase rounds can make the base too small or too large; count your DCs after rounds three to ensure you have 24 then 36 before building the sides.
✗ Skipping the instruction to add stitches for cotton blend can lead to a tight fit after wear; if using cotton blend add 2-3 stitches after the 3rd row as suggested.
✗ Attaching the pocket without checking placement can look crooked; place the pocket between straps on the bottle and pin before sewing to ensure it sits straight.
