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
Bonnie Babies mainly makes blankets for premature babies. They provide patterns for toys, hats, and sweaters (including a ”5 Hour Baby Sweater!”), but blankets are quick, simple to make, and guaranteed to fit. Families can then continue to treasure them long after the child is grown.
If you click on the resource link at the bottom of this article, you find hundreds of free patterns that will pique your interest. Under the image, Knitntyme specifies ”gauge/tension, number of stitches per 10 cm/4” or crochet hook. Suggested yarn may be replaced by yarn with a similar knitting tension.” So you don’t have to buy their yarn to download the pattern.
Bonnie Babies: This charity sends premature baby outfits and blankets to special care baby units around the UK and to parents who need support. A mother who needed a way to deal with the loss of her premature child founded Bonnie Babies six years ago. Bonnie Babies makes premature clothing, blankets, and burial outfits for U.K. Special Baby Care Units and families. Their aim is to show each mother and family that there are people thinking of them and caring for them.
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.
