Congrats! As to what to do, when my DH bought me a beautiful Bernina 440 QE a few years ago, I learned to use it by making 37 pillow cases for the million pillow case challenge. Not only did the local homeless shelter get a bunch of pillow cases, but I learned a lot and really put the machine through its basic paces. When I took it in for its first (free) checkup, the repair people were surprised by how much sewing time it had on it already. No kidding! Making 37 pillow cases is not a task for a single evening.
