Well... we really don't know where it comes from. My mom "asked" to Google for some info but she could not find anything! But, 5 years ago a friend of my mom gave to her the first one. Her friend told my mom to put it on her Christmas Tree. Right on the center of it so the lamb gets all the energy from the lights and ornaments. Then, the first day of the year you need to put it on your front door. The lamb needs to have a red ribbon around its neck. The "tradition" says that having a lamb on your door lets the abundance to come into your house. Wool in spanish is "Lana". A common way to name money here is "Lana". Soooo... the lambs with their wool mean... They have the money! And... very important... you must not buy the lambs. Someone has to give it to you as a gift. What do you do with the lamb from the last year?? You have to give it to someone else to share your good fortune!
My mom says that the "abundance" has not come into our house but we have enough to live everyday without worrying if tomorrow we will have something to eat. And that is very important, right?
