I sew on a Viking Sapphire and I love it. This is my second Viking. My first one is still going strong for my Mom. I kept the first one for my daughter to learn to sew, but she wanted to sew on the new one. My Mom needed a new sewing machine so I let her have mine. I was so glad I had it to give to her. That was worth far more than any trade in value I could have gotten. My Mom has done so much for me over the years, I was happy to be able to do something for her!
