Some good advice here…..
knit a square in stocking stitch (if you plan on using a stocking stitch for the majority of your project- try to knit the same tension you always knit.
Cast off once you have a square – mark down in your notebook under ‘swatch’ how many stitches you cast on – with what size needles and then what size needles you do the whole swatch with.
Once you have a square — you will then carefully count the number of stitches over 4 inches — ( I use a little tool for measuring my swatch – see attached picture. It is very handy – you lay the measuring tool on the knitted swatch IN THE CENTER OF THE SWATCH – NOT AT THE EDGE making sure that you have
one side of the opening on the edge of a stitch – The opening is 2″ long and 2″ tall — carefully count how many stitches there are in the two inch window horizontally – and mark it down in your notebook. cut that number in half and you will have the STITCHES PER INCH.
The vertical opening is done the same way, only you will count the number of ROWS in the two inch vertical window — and mark it down – then you will divide that number in half and you will write down the number of ROWS PER INCH-
NOTE – it is best to get a counter like the one I have shown you – but you Can., if you are careful -using a flat ruler and measure two inches in the ‘center’ of the swatch- and count the number of stitches, figure out your stitches and rows per inch. I would suggest you try to find the counter as I use mine all the time.
Note: you might want to buy an extra ball if you plan on doing cables or a pattern that increases stitches
– You should do a swatch of a sample of your addition eg. cables – and incorporate the extra
stitches in your pattern.
