Knitting gauge help

[yaela123]

I've knitted a gauge swatch for a pattern which is supposed to be 11.5 stitches and 22 rows = 10 cm

Except mine is 19.5 stitches and 23 rows = 10cm

How can the stitches be this far off but the rows almost correct?

I'm not using the recommended yarn - could this be related?

Try again with the correct yarn.

How can you have 0.5 of a stitch?

Oh I suppose you could measure to the centre of a stitch.

Are you using a much thinner yarn than recommended? Maybe try holding two strands at once?

You will need to go up a few needle sizes too if you hold it double.

What are you making?:)

The correct yarn is too expensive

I realised my yarn has a smaller recommended needle size so I might try again with a new yarn with the same recommended needle size as the pattern.

It's for fingerless gloves
