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.
The charities involved usually have free knitting patterns and advice on their websites so do not be worried by all the details as you really will be able to find a garment to suit both your knitting skills and the babies needs
Feed the Children: Feed The Children is a UK charity that has a knitting pattern for a jumper appropriate for children of all ages. They are also look for knitted hats, gloves and scarves.
Color Outside the Lines: I remember coloring books, and how careful I was to never get the crayon color outside the area I was coloring in or it would be ruined. Not so with knitting. Especially with scarf knitting. Because of all of the yarn choices we have, putting together beautifully color-crafted scarves is so easy. And so fun.
Colours: Pastel colours are the most popular. Apart from baby pinks and blues other colours, which may be chosen, are: Lemon, Cream, White, Mint Green, Peach, Lilac and Aqua. It is accepted that bright and dark colours should be avoided as they often make premature babies look frailer. When knitting burial garments the advice suggests its best to use colours such as white or cream and to avoid pinks, blues and lilacs, as they are not appropriate for the colouring of a stillborn baby.
