In this lovely little jumper worked in 8 ply luxury wool yarn fro Bendigo Woollen Mills I have followed a traditional Patons pattern from their book Totem book No 952, Jumper no 2. This is illustrated with a polo neck but I changed this to a round neck to update it. 
The designs from this era are very classic, but polo necks somewhat date them. When following any of these designs it is important to be aware that they are very fitted. Most modern knitwear allows for greater fullness, so you may need to go up a size to get an acceptable fit by current standards. 

I have transformed this little raglan sleeved jumper pattern by using a decorative band on the front and back. The divided triangles design is worked over 18 rows. Multiple of 14 +1.

Rather than using the traditional k1 P1 rib for the bands I have used an uneven or mistake stitch rib which gives a more textural finish.
