i have two (not counting an embroidery machine) and sometimes wish I had three. my janome i use for machine quilting. the other i use for piecing. it's great because then i don't have to switch out the feet all of the time (darning vs. even feed). if i had another machine, i could keep my 1/4" foot on it and i'd be good to go!
is that the height of laziness, or what? :shock:
oh, and in my own defense, i typically have 2-3 projects going at once. one being pieced, one being quilted, and one (or two) something else.
