This set is continuation of my crochet families. It is made from different yarns - wool, socks yarn, mohair and cotton. Structure for hollow gives thick felt. Almost all parts are crochet only big owls are crochet and embroider. Like in my sparrow set, eggs can be open and chicks taking out. Hollow is 18 cm big.
