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.
Cowls: Now, here is a project that is hotter than hot. Cowls, aka mobius knitting is all the rage right now. And no wonder. These little beauties are attached at their ends when finished and they are also called Infinity scarves. Besides looking just terrific with any wardrobe, cowls are the best warmer-uppers on cold winter days. Easy to knit, they can be finished in a weekend.
Fastenings: Plain flat half-inch buttons are best to use for fastening. Avoid nylon and metal fastenings, as they get very hot under the incubator heaters. Do not use Velcro as a fastening, it is very scratchy on the hook side and also damages knitted garments when they are laundered. Ease of dressing is vital for preemies and as a general rule it is best not to use ribbon as a fastening as ribbon can often be fussy to tie on a garment so small.
One of the first accessories that will become invaluable for you as a knitter is the knitting bag. This type of accessory does not only provide the perfect place to store your unfinished projects, your yarn and your knitting needles, but it will also allow you to transport your materials with you without worrying that they are going to become damaged.
First and foremost it will be a great way to spend some quality time with your son or daughter. (Yes boys can work with yarn too!)
