I carry my little Featherweight with me in the travel trailer. I only use it for piecing, something it excels at. I don't consider it a replacement for my beloved Bernina 440 with its multitude of stitches, needle down, etc. I really don't have the space to quilt anything in my TT, just piece, so it works for me. If I have thought about doing anything other than piecing, I bite the bullet and bring the Bernina.
I find it hard to switch machines while piecing. Even though I carefully adjust both machines for what I think is exactly the same stitch width, there seems to be a small amount of variation that drives me nuts. For that reason I try to do smaller projects on the FW, something I can get done relatively quickly.
