I created this little argyle vest for my nephew, little Marko, about 18 months in the picture. He is a giant for his age so I made the sweater for size 2 to 3 year old so he can wear it more than 5 minutes :-)
The vest is knitted bottom up, back then front. A chart is provided for the fair isle design.
The wool/cotton blend is perfect for all seasons as little boys love light vest to play around.
