Knitted baby romper pattern

Knit Karine Strand Andresen’s gorgeous Nordic knitted baby romper pattern for the ultimate new baby gift.

knitted baby romper

We can’t resist a Nordic knit, especially when it’s as out-and- out adorable as this tiny romper. Worked in a soft, muted
yarn that’s delicate enough for newborns, the intricate details in this mini design are inspired by traditional Scandi knitwear. It’s cosy enough for autumn days, and makes a thoughtful gift for mamas with seriously on-trend offspring.


The romper is knitted top-down
in the round on circular needles. The pattern is given in four different sizes, but written for the smallest size. The patterns for the larger sizes are shown in brackets, increasing in order of size e.g. 1 (2, 3, 4) sts.
