The swatch I need for this DK jumper I need is 18sts x 24 rounds on 5mm needles - I’m a firm knitter so I usually got up 1/2 a size. With 5.5mm needles, I knitted a swatch 26 sts (4 sts in garter st on either side) and 28 rows in st st with 6 rows garter st top and bottom to create a nice flat piece.
5.5mm: The fabric was quite loose (too loose for a jumper) and my 10cm swatch used 18 sts and 22 rows.
I re-swatched in 5mm: The fabric is perfect, but my 10cm swatch uses 20 sts and 26 rows… The pattern says that gauge is crucial…
Neither swatch was washed and blocked - not enough yarn
I would really appreciate your comments. Thank you!
