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.
Other types of stitch markers on the market today can be clipped onto you project when needed, and then clipped as required. These allow the individual who is working on the pattern to come back to a certain place in the design later in the project, leading to a great deal of precision in the creation of the project.
The charities have a lot of information on their websites, below is some general advice to help you get those needles clicking.
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.
