Free cocoon patterns for newborns are generally easy to crochet. Patterns vary from a tube closed at one end to a rectangle fastened together with buttons.
Several patterns are composed primarily of double crochet or half double crochet stitches. Both stitches work up quickly, but the half double crochet stitch doesn't leave gaps in the work. A shell pattern looks nicer than a plain double crochet stitch, but the gaps can be big enough for fingers and toes to poke through. Most patterns start with a magic circle or slip stitch ring, then stitch in the round to the top. If the pattern has a flap, the bottom of the pattern is stitched in the round and the flap is stitched in rows. The buttons are sewn on the flap opposite of large gaps that function as buttonholes.
Free patterns available on the Internet include simple cocoons, caterpillars, animal themes and holiday themes. Yarn used in the patterns include inexpensive yarn such as Red Heart Love and Caron's Simply Soft, baby yarns such as Bernat Baby Boucle, and organic yarn such as Lion Brandﾒs Natureﾒs Choice. Some free patterns are downloads, and most yarn companies require signing up for a free account to view their patterns.
