If only someone at Land of Nod had read the Betsy-Tacy books! The Knit Crowd dolls are almost perfect replicas of Betsy, Tacy, and Tib as they look in Lois Lenski's illustrations for the first four books. Just switch the hair color on the brown and yellow-haired dolls and shorten the braids, and you have Betsy and Tib (the ballet dress is better on Tib anyway). And Tacy's red (orange) ringlets are exactly right. Sadly, all three dolls are sold out til early February, but that just means you have time to reread the books, conveniently reprinted in the The Betsy-Tacy Treasury by Maud Hart Lovelace (William Morrow, 2011). I still have my 1970s Harper Trophy editions; judging from their condition, Betsy-Tacy and Tib was my favorite. This image is from Chapter II, Learning to Fly.
