When a fashion stylist with a penchant for knitting has a baby, it’s no surprise that a new business is also born. Anna Wallack, who founded Misha and Puff to create warm and cozy knits for little ones, is offering her collection along with gifts by other like-minded brands at her first Boston pop-up shop, open through Christmas Eve. Adorableness abounds, including puffy bloomers done in a popcorn stitch, pointy top bonnets that button under the chin, pompom trimmed ponchos, and fisherman ribbed booties with soft leather soles. Each piece is hand-knit by Peruvian women in Lima using hand-dyed merino and alpaca wool. North Wind coat (above), $198 at Misha and Puff, 91 Newbury St. 617-522-4046.
