Size: Don’t put too much importance on trying to perfect the size of a preemie item of clothing. There is a great difference between premature baby sizes and so an item of any size should be suitable for at least one baby. As a general guide premature babies head circumference is roughly the same as their chest circumference. The average premature babies chest measurements are 8”-14”. However clothes of all sizes are needed for preemies, so no matter how big or small your item is it will most likely fit at least one baby.
The blocking mat is another accessory that can be extremely helpful for the knitter or crocheter, or even for those who enjoy sewing and quilting. This mat serves for pinning the project to its surface, making it very easy to line up the project, keeping straight edges, hems and seams.
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.
