This Baboushka doll is filled with toy filling, but you could add weight to the inside (such as a bag of gravel) to make this into a weighty doorstop or bookend.  Designed by Amanda Berry @fluffandfuzz, the doll is knitted in acrylic DK yarns on single pointed needles (not in the round), and the apron has a single crochet border.
