1) Should I pin my quilt on the leaders or baste them on?
Find the center of your top (and back). Mark with a pin. Start in the center and pin every 5 to 6 inches. Then go back and put another pin in between.
2) If I want to quilt something that does not have a continuous pattern how do I lock my stitches before I cut to go to the next block?
Lower the needle once. Then move it a few inches and pull up the bobbin thread. Pull on both threads and stitch in place about 3 stitches. That will secure the start of your sewing.
3)My table has a adjustment up and down. How close to the floor of my machine do I want to set it? The lower I go it seems like I will not have no roll up space to quilt anything with size to it.
When I am sewing at the back of the machine, I like it about waist height. When I am at the front of the machine, I try to get my elbows at about a 90 degree angle when holding onto the controls.
