I know this might be a strange question lol.. but i'm really interested in making some clothes or bibs for Ellie.. and a blanket and some other bibs by using my mums sewing machine.. but.. i'm a bit stuck as to what kind of material to use.. I know that baby grows/vests would be cotton.. but would it be poly cotton or what? and bibs I'm guess terry towel material?? Any other ideas??
