I have two machines - a featherweight and a Viking. I like my featherweight cause it's easy to carry from room to room. I lay out my quilts on a bed in the basement so the machine goes downstairs for that. Also the laundry room is downstairs so I can get a little sewing done in between loads. Sometimes when the grandkids are visiting I like to piece while they're watching TV so then it comes upstairs. My Viking has a large throat so I use it for quilting. When I get the tension adjusted I like to leave it alone till I'm finished so then I can use the featherweight for piecing. The Viking has decorative stitches and I also use it for piecing.
