I keep a clear plastic bag taped to the table where my sewing machine is to keep all the threads I cut, etc. in. However, the cat is always on the table or nearby when I sew. He could put his paw into the bag to get the threads. I am careful about the pins also. The magnetic pin cushion waved over the area where sewing takes place is a good idea to get the pins which have fallen. I do find pins on the floor under my desk/table where I sew. Thanks for the info on the threads being dangerous to cats.
