Like the child in the sand box, I'm keeping all my toys.

I would keep the Luminaire too. That way I can sew or use the embroidery features. If there is no electricity, I won't be stitching anyways.

I would keep my vintage Pfaff 130. I use it mainly for applique because of its ability to do zigzag for applique, but lately I've been also using it for some piecing and for my FMQ and ruler quilting too. It's not a treadle, which is its downfall in regards to doomsdays, but my hubby is an electrician so I'm sure he could rig something up. https://cdn.quiltingboard.com/images/smilies/wink.png I do have a treadle, so if I was allowed to keep two, the treadle would be my second.

this is a tough one.
i have four machines now.

Dream Machine2
Janome Skyline S9 (for travel)
Janome Continental M7 (because i am ridiculously self-indulgent when it comes to machines)
big-box Brother (backup travel)

i guess if i absolutely had to limit myself to one it would have to be my Brother Dream Machine2.
it doesn't sew as well as either of my Janome machines but comes tolerably close.
it has a large work area, is embroidery capable, a scanner, and plenty of other bells and whistles.
it isn't easy to travel with, but i have done so and could again if necessary.

a harder question for me to answer would be which machine to buy if i had none and could only get one (without having to consider cost.)
there's nothing on the market i know of that includes everything i consider essential for top-notch embroidery plus greatest sewing.

Jingle i love your answer. i would keep all of mine. maybe in a year i will add another Bernia. i have 4 Janome

and one Bernia.

I am down to only 9 machines right now and would not give any of them up! I have 4 singer 221s and 4 Pfaff's 7570s I use them for my 4H classes and for my own sewing. Waited too many years to get just what I wanted, and I don't have all that many years left, so keeping what I have as long as I can!

Mine will all stay right here. I could never choose just one. I have a Singer Treadle , 2 Featherweights, Janine, Bernina, 2 Vikings and all are loved.

Let's make it tougher - you live in California and you are fleeing the fires -

If you had time to grab a machine - - - - and had room in your vehicle -

Oh bearisgray that is a really tough question and at this time I am leaning toward.......................................oh shoot I can't decide lol, Probably my Brother embroidery/sewing combo machine but please don't take away my vintage ladies as I love them all.

Oh wow now you really are making it hard but probably my featherweight.

Right now the only one I would take because of sentimental value is a dinky mechanical Brother XR-57 which is over 15 years old and still works great. I learned to FMQ on it. Any others I could do without or find again including featherweights.
