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.
The charities have a lot of information on their websites, below is some general advice to help you get those needles clicking.
Have you knitted for your children? Your grandchildren? Your friends’ children? Your friends’ childrens’ children? Knitting baby clothes is quick and rewarding but sometimes there are just not enough babies in your social circle to knit for. If you love knitting beautiful little items of baby clothing then why not think about charity knitting for premature babies?
Finally, one essential accessory to keep your equipment safe is a set of knitting needle caps, which are designed to be placed over the end of your needles when they are not in use. As mentioned above, needles can cause damage to bags that they are kept in, and can even prove a safety hazard, especially if they fall into the hands of children.
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.
