Yarn: Premature babies have very delicate skin and can often be allergic to wool; therefore it is best to steer clear of garments made with a wool mix. Acrylic yarn is more appropriate when knitting for preemies. Ideal yarn to use for preemie knits is baby double knit or 4ply yarn. Most preemie patterns will use these.
Other smaller accessories that can be particularly useful when working on a knitting project are stitch markers, which can be used to mark particular points in a pattern that you are working on. These often come in the form of small rings which can simply be slipped onto your knitting needles as you knit.
Knitting items for premature babies can be very worthwhile and rewarding. It is definitely appreciated by the charities and the families who receive them. If you are excited by the prospect of getting your knitting needles working for charity and want to explore charity knitting for other organisations here are some other ideas to help your search.
It may take time out of your schedule but there are many benefits to teaching and allowing your children to join you in your favorite hobby.
Confetti Yarn: This yarn is very lightweight and soft as soft can be. It usually comes in pretty pastel colors, just perfect for knitting for baby. You can use this yarn with another, or on its own. I used confetti yarn when knitting a blanket for my granddaughter Julia. I alternated rows of confetti with rows of another soft pastel baby yarn. The results are wonderful.
