This is a pattern for a baby-vest with a vintage retro inspiration in 3 sizes :
0-6 months : back measures 24 cm (9.6 inches)
6-12 months : back measures 26 cm (10.4 inches)
1-2 years : back measures 29 cm (11.6 inches)

The pattern is fully written for all 3 sizes.

These vests are completely seamless and they are worked from the top to the bottom in 1 piece (top-down)
There is almost no counting to do, so it is ‘a happy crocheting project’.

It needs a bit of experience.
Beginners will also be able to make these vests, but maybe they prefer to skip the two-colour parts and make these vests in 1 colour…
