The Hammer ~ that's called percussive maintainance.
The trellis - Use your ruler to draw diagonal lines both ways across your quilt, you should wind up with diamond shapes. I use Crayola washable markers. They come in great colors that show up on every color fabric. Then just stitch on the lines. Guess you could make them straight across and up & down but I think the diagonal lines would be more appealing to the eye. Good luck. Glad you got your machine fixed.lol
