Very nice quilt for your first one!!! As a novice quilter, probably keep the quilting simple on this one. Stitch in the ditch is good, quilting with diagonal lines works well. You can use masking tape to mark lines. Place the tape, quilt along the edge of tape, then peel tape away. You can re-use the tape as long as you don't sew into it. You can also use decorative stitches on your machine. There are no rules. Just have fun!
