Pin your layers together making sure everything is flat and smooth. I often use masking tape to tape down the backing on my large table so it won't pucker. Smooth out the batting and then set the top on top of the batting. Once all three layers are pinned together, use your walking foot and machine quilt (lengthen stitch) right down those seams using the stitch in the ditch technique. Start in the middle and work out. This is a perfect quilt to start machine quilting as it isn't too large and your blocks aren't too big either. Happy machine quilting. You can do it!
