My machine came with an extension table & all it ever did was pi$$ me off! Stacking books all around worked much better for me before I got my sewing cabinet that the machine can sit down inside of.
Stack as much stuff as you can think of all around your machine to the back, front & left. You might want to try the kitchen table instead of a sewing cabinet to give you more elbow room.
There is someone on this board that bought the insulating styrofoam panels and set them all around her machine. She also turned her machine so that she was facing the nose. She then had more room to work left & right and would just roll up one side instead of 2. I wasn't that smart & gave up & bought a quilt frame--LOL!
