I have two original 1930s quilts made by my great Grandmother. One a Log Cabin, the other a Grandmother's Flower Garden. Both are hand quilted with outline stitches, no motifs. I have seen other vintage quilts with motifs, like an american eagle, in the middle of cross hatching. Maybe you could check out some of the books on reproduction 1930s quilts in your library, there is usually a suggested quilting patten for each quilt but it might not me mentioned in the book description online.
