I don't know how to use the darning on my bernina 950. Can you advise

You need to use a darning presser foot--there are several designs of darning feet made by Bernina or generic brands (be sure the generic model has the appropriate attachment for your particular Bernina). You can find metal or plastic, clear or solid foot, open or closed toe, spring-loaded hopper or not, etc. Drop the feed dogs. If it is thinner fabric (lighter weight than denim), it sometimes helps to put the fabric in an embroidery hoop (upside down with the fabric next to the needle plate). If the hole is small, you can use the little hoop that should have been included in your Bernina accessory kit. Then you manually move the fabric back & forth, up & down under the presser foot while stitching.
