I stared to crochet for new babies when ever I got invited to a baby shower. I crochet the sweaters big enough so that the new little one can grow into them. I all got started about the time the little one in the top picture was born. He is in middle school at this writing.
Then I showed them to my step-daughter and she liked them so well I was then asked to crochet some sweaters for her “Reborn Babies” that she makes. Because she sells more of them to people at Christmas time they look even cuter wearing a crocheted hat and sweater set. They wear a newborn or even a preemie size sweater so now I have been crocheting them to fit a 3 to 5 pound baby. The yarn I use is thinner than what I use for the 18 month size and so the hook I use is smaller too by believe me there is the same amount of work that goes into crocheting them.
I crochet the Reborn Baby sweaters the same styles as I crochet sweaters for human children
I was told that weather can damage their “skin” so the Reborn Babies must be covered so they do not get cold or melt. Because it is hot where we live we cannot leave it in a car when we go out any place. We take it into the stores and restaurants with us. This draws attention when we are out with one but the crocheted sweater and hat get noticed almost as much. That is good business for me. I get to make a sweater and a hat for each one sold to someone.
