I'm a left handed quilter too. It sounds like you have a quilt hoop. Sometimes turning the hoop allows you to continue in the direction that is most comfortable for you. I have a lap frame and a floor frame. With my floor frame there is no moving that frame around to move things around. What I do when quilting circles or feathers is to only take two stitches at a time until I just can't go any further. I might then resort to doing a stab stitch to complete the element but usually I will stop at the point things get to "standing on my head" and attack that element from another angle. I can say that practice with those "standing on your head" areas will make things a bit easier down the road.
