I too have a long arm (coming home on Sunday - yippeee!!) but I have quilted large quilts on my domestic. It can be a headache and some designs are just easier on a long arm because of the freedom of movement...but truthfully if you mark and sew carefully you can do just about anything on a domestic that you can a long arm. I also quilt in sections and it helps to quilt in a table or somewhere you can lay the section of the quilt that is NOT being quilted. Turning and pivoting for intricate designs can be a real headache...but before I could convince the Husband that I just NEEDED a long arm I had the motivation to do it on my domestic and I did. (But don't tell him that...)
