We would like to have a sewing machine for the Lab.
I have never done machine sewing, only hand sewing, so I know nothing about sewing machines.
Projects we would like it to be able to handle include window quilts, which involve wool thread and fabric and ~5-inch-thick wool batting (see pictures below). It would be great if it could handle the quilting, too.
Also we would eventually like to be able to upholster couches and chairs, make mattresses to stuff with natural materials, make quilts/duvets, etc.
Also we would like it to handle clothing repairs (including insulated coveralls, canvas jackets, etc. as well as lighter things like tee shirts).
Is there such a sewing machine? Preferably one that isn’t astronomically expensive? Repairability is also a plus.
