About This Granny Square Pocket Bottle Holder Pattern
This pattern creates a slim, strap-style bottle holder with a mesh body and an optional granny square or solid pocket for a phone. It uses DK (8 ply) cotton and simple crochet stitches, so it is quick to make and durable to use. The design stretches slightly for a snug fit and includes two strap methods so you can choose what suits you best.
You get two pocket options in one pattern: a granny square pocket and a plain solid colour pocket. Clear step-by-step photos and measurements help you check fit as you go.
Why You'll Love This Granny Square Pocket Bottle Holder Pattern
I absolutely love this pattern because it turned a simple practical request into a fun, portable project I use every day. I enjoy how quickly the body section works up into a neat cylinder and how the netting makes the holder light and breathable. The granny square pocket is a playful detail I adore addingβit's great for customizing with scraps. Making the strap in two different ways gives me options for stretch and durability depending on how I plan to use the holder.
Switch Things Up
I love how easy it is to customise this pattern with colourβtry bright stripes for a festival-ready look or tonal shades for a more subtle everyday piece.
Change the yarn weight and hook size to adjust scale: bulky yarn with a larger hook makes a chunky, cosy holder while finer yarn makes a delicate mini version.
I often add a metal snap or small button to the pocket to keep a phone secure; sew it on before attaching the pocket to the holder.
If you want the strap to stretch less, crochet the handle horizontally and use 3 rows of HDC, or back the strap with ribbon or fabric for reinforcement.
For a keyring or bag charm, make a tiny version using thinner yarn and a smaller hook, and attach a metal keyring to the strap end.
Try decorative edges around the granny square pocket by adding a round of picots or a contrasting sc border for a polished finish.
I sometimes make the body entirely in solid HDC rows (no netting) for more insulation or for smaller bottles that need a snugger fit.
Swap the granny square pocket for a lined fabric pocket if you want more protection for electronics, sewing the fabric in before finishing the top.
Want a longer carry option? Make the strap longer (measure across your body) or add adjustable hardware like a slider on a reinforced strap.
I also enjoy adding tassels or pom-poms to the drawstring ends for a playful touch; they make the holder feel handmade and unique.
Common Mistakes & How to Fix Them
β Not checking gauge before starting can make the holder too loose or too tight; measure 5 DC per 3cm and 4 rows DC per 4cm and adjust hook size accordingly.
β Using a cotton blend but following the exact stitch counts for cotton will result in a tight fit that does not stretch as expected; add 2-3 stitches after the third row if using a non-stretchy cotton blend.
β Failing to measure the cylinder on a water bottle during the build can lead to a poor fit; test the body on the bottle after 4 rows to ensure it fits snugly but can still be pulled on.
β Sewing the pocket or strap without leaving long tails can make finishing awkward; always leave a long tail for sewing and a 20 cm tail for securing the strap end.
β Attaching the strap unevenly will make the holder hang crookedly; fold the bottle holder in half and sew the strap ends evenly to opposite sides to keep it balanced.
