This pattern can be used for covering a jar approximately 8cm wide. I used a cheap, small storage jar from IKEA but any jar of a similar size will do.

The Tree part of the pattern is made in multiples of 4 stitches so if you need to make yours a bit bigger or smaller adjust the base size so that your last row has multiples of 4 stitches around.
