Before marking and cutting
- US inches; feet where appropriate. Metric values are rounded references. Written inch values control.
- 3/4 in means measured 0.750 in actual thickness wherever used. Recalculate mating lengths for other sheet thicknesses; do not substitute nominal stock blindly.
Use limits
- Grip cover only; not a hot-liquid protector, bottle harness or validated insulation product.

Assembly
- Measure the bottle circumference. This sleeve assumes 10 in circumference and leaves closure overlap; it must not cover the cap or required labeling.
- Cut A and B each 12 × 9 in and C 11 × 8 in. Do not use this on hot-liquid bottles.
- Put A and B right sides together. Sew a 1/2 in seam along both short sides and one long side; leave the other long side open.
- Clip bulky corner allowance without cutting stitches, then turn the shell right side out. Its intended face is 11 × 8 in.
- Slide C into the shell and smooth it flat. Turn the opening allowance inward 1/2 in and stitch closed.
- Sew a vertical quilting line at X = 5 1/2 in through all layers to prevent batting bunching.
- Sew a 1 × 6 in loop tape vertically near one short end and matching hook tape on the opposite back face, leaving 1/2 in edge margins.
- Wrap around the capped bottle and mate the tape with about 1 in overlap. Check the base of the bottle remains fully exposed and level.
- Grip the bottle by its body above the sleeve before lifting for the first trial. If the sleeve slips, do not use it as a carrying handle.
- Remove for washing; dry separately and inspect the bottle’s own cap and body.
Checks
- Finished sleeve near 11 × 8 in with 1 in overlap on stated bottle.
- Bottle bottom and cap remain unobstructed.
- No carrying handle or temperature-holding claim is made.
Cleaning and maintenance
- Remove daily if damp.
- Wash and dry all layers completely; inspect closure stitching.
