I've had my Sapphire 870Q for about five years. Once I found out what brand of thread it liked I was off and running. I make all of my quilts from beginning to end on my 870Q. I purchased a Free Motion Quilt foot and have quilted all my quilts on my Viking. Since I have very tall (two are 6'7") men in my family I do the FMQ in two parts and then sew them together. Like Georgia Bonestill's method.
