Shamrock Tea Cosy
This pattern can be found here:
Notes: Due to ribbed nature of stitch, fits any regular teapot snuggly. If required can easily adjust width by increasing/decreasing by 4 stitches, with out affecting stitches for decrease at the top. Will just need to do more or less decrease repeats across the row.
I used a small circular needle knitting back and forth for convenience, but single point fine.
The yarn I used is classed as chunky (pattern suggests Aran/worsted) l didn’t find however that I needed to adjust amount of stitches still knitted up to correct size .
