Hi DJ, yes the diamonds were quilted after I had attached the backing, it was doable on my dsm. I live in UK and dont have space for a longarm much as I would love one, my dsm is a JanomeMC4000 which is 20 years old and only has a 7 inch harp. I am planning on buying a machine with a much larger throat later in the year, but at the moment I manage to get by.
