Below is a baby blanket I knit for my second niece, Constance (I'm getting a third one soon!). I tried out a blend of cotton and merino wool to get both softness and warmth. The results were interesting as the colours I selected here were a perfect blend, however going forward I will probably try to blend colours that more closely match. I used a wheat colour in a worsted weight cotton, and a mint green sport weight baby merino wool blend. The heavier weighted yarn is definitely at the dominant colour, but the hint of mint green adds a nice touch. I'll be posting some other blending experiments in the near future.
The pattern I used was an interrupted rib 3X3.
