You made me laugh as I realized I DO have 2 that I use at the same time.....or on different sections of the same block. :D
I piece HSTs and other triangle type sections on one machine where I can not use my sticky-note-pad-1/4"-seam-barrier trick, and the other where I have the barrier set up for a straight 1/4" seam. :) I just move down the table length from one machine to the other, SEW handy.

I only have 2 machine. I use both a lot

I have several sewing machines (mostly Singer). I oil and clean each and everyone after I complete a project. The three newer ones don't need as much cleaning. The Vintage Singers are lubed and oiled after each major project and I do use different machines regularly.

I don't think so. Crazy is spending thousands to do just straight stitch and zigzag on a plastic machine that you can't fix when you can get a reliable, fixable one (that occasionally carries the elusive scent of Cologne de la Huile) for less than 100 bucks.

Good reminder! I keep one of mine threaded with black so use it more often than the other one. Just remembered the FW I haven't used in a long time. Will get right on it!

Mine goes to retreat with me twice a year and to any classes I take.

I sat and sewed on my featherweight all summer. I just recently changed the needle and oiled her. and you're right I then thought about the other machines and slowly pulled them out and clean them up & oiled whatever machines needed to be oiled. my janome says not to oil. don't understand that, so I just cleaned her up.

I'm in the process of rotating my machines right now. I just added two to the herd and I figured I better give some of the old girls a spin before I get the new ones in to play with.

I also keep an inventory of my machines for my dear daughter who inherits all my worldly goods. My inventory lists each machine, model no., serial number, how much I paid for them, when I bought them, where I bought them, a list of presser feet and accessories, and a brief description of the kind of sewing they do. This way she'll have a pretty good idea of the worth of each machine.

Good point!
