I prefer to work on worsted weight blankets, although I will knit on preemie blankets, too. I like the size of the needles better on the WW ones.
Purple Mountains Majesty (purples and blues)
Desert Sand (tan, beige, pale green)
Disneyland (bright colors)
Rain Forest (greens & yellows)
I prefer to place a card in the package because it costs less to mail than the notebooks.
