My "good" machine was lost for quite a while. I was sure it was in the front bedroom but I wasn't sure. After I moved, My para from school came over and stacked up all the boxes in the front bedroom up against the front wall leaving the heater vent enough room to vent. Well, I could get in the room after she did that. I thought my machine was on a closet shelf in there. When I looked in the box that was on the shelf - it wasn't my sewing machine. I bought a refurbished machine off craigslist. I was frustrated! Well I decided that I would clean and get rid of everything in the front bedroom that I could do without. Well, guess where my machine was! Right up against the front wall of the room almost in the opposite corner from the door. I can sure sew better now.
I pray that yours is not that hard to find! You are not alone.
