I use a size 12 needle that some may find too small. It's a personal choice, but I've found that if I use a small needle, I can get smaller stitches. I also use contrasting quilt thread that forces me to do better work. I do believe that every hand quilter determines what works best for her/him.
Like others on this Board, I return to hand quilting because it's so relaxing. I have my quilting frame set up in my living room where I can listen and watch the television while I am quilting.
Another note: Do not be discouraged when you start to hand quilt because a curious thing has happened with my own quilting. I cannot do the extremely small stitches, but my stitches are even and regular--good enough that my hand quilted top won a Blue Ribbon at our local Fair. :lol:
