I have numerous machines that have been collected over the years. The one used exclusively now is a Janome 4623LE. This is a basic machine, yet a solid workhorse. I use it for piecing as well as machine quilting. Some day when I am rich and famous, I would love to have the Janome 6500 or the 6600 with the larger throat plate. If anyone out there wants to make my dreams come true, my birthday is in September. LOL
I also have a serger that gets use when sewing strata for charity quilts. There is nothing that can sew as fast. I also use it to finish garment seams.
