I just finished quilting a paper pieced quilt on my Janome Horizon 7700 and boy was I sore afterwards. This quilt has by far the most quilting of any quilt I have done before and my back and shoulders felt like they were on FIRE. It didn't help that I set myself a ridiculous time frame to finish it

I am saving up to buy a long arm, might take me a while, but I will get there.
