I always see the beautiful machine quilted quilts here. I want my pieces to look something like them and was wondering what kind of thread is the right thread to quilt with. When I try to quilt my pieces with the machine, it seems that the thread does not look as thick as the ones I see here all the time. I guess i use regular cotton thread to piece. So what thickness does the thread suppose to be for the quilting part and what brand shall i use? Please help :-)
