I just made three (3) utility quilts with the maple leaf pattern and I think your leaves need a stem. A stem would fill the hole where a stem should be. The pattern I used had a straight strip (3/4 inch wide cut) in the bottom left corner, where you have a half square triangle. You take a background square and cut it on the diagonal (from one corner to the opposite corner), place the strip between the two triangles and stitch a 1/4 inch seam and viola, you have a stem.
