How to Do this

Founding the Foundation
Make a chain long enough to go around your jar. Join carefully, no twisting.
Work the Main Section
Crochet a base round and then continue in waistcoat stitch to build the body of the cosy. Keep your stitches even so that the fabric looks neat and sits well on the jar.
Change the size
Take the cosy along on the jar. If you want more coverage just keep adding rounds until it’s the height you want.
Edges of Edges
When the cosy is the desired height tie off and weave in the ends neatly.
Helpful Hints
- Mark the beginning of each round with a stitch marker.
- Instead of guessing, check the fit frequently.
- Be sure your tension is relaxed, especially with waistcoat stitch.
- Weave in ends well to ensure the cosy will stand up to regular use.
Reader Mistakes to Avoid
- Chain too tight to start.
- Attaching the base after conforming
- Tight pulling of waistcoat stitching
- Failing to check the fit on the jar
- Stiffening short of tying the ends tightly
Ideas for Customisation
- An easy colour-block look is achieved with stripes.
- Increase its height for more coverage.
- Home decor jars in soft neutral shades.
- Bright colours make wonderful gifts or seasonal table settings.

Care Instructions
Wash by hand in cold water, if needed. Lay flat to dry. Reshape whilst wet. Do not wring hard, to keep the stitches in shape.
Time Required
