Need ideas on quilting this 40 year old quilt
[ATTACH=CONFIG]601614[/ATTACH] I was asked if I could repair this quilt, it was the ladys son's quilt and he loved it so much - he was in an accident at his job and passed away, however she has been looking for someone to fix this quilt. I have now fixed 20 areas of frayed edges, holes and pulled stitches, and now I am ready to add new batting and backing, however before that I need to requilt it, and need your assistance on how should I quilt it, in order I don't take away from the quilt. I think it is an old string quilt, so all the pieces are stitched down. Any help would be appreciated.
