FIX UPDATE: my friend and I did the fix today for the icky seam. Fray checked all the edges. We took a piece of the blue flower print, tucked under a 1/4 inch on the triangular sides and tacked it down over the existing patch. A half inch of that print fabric went under the white border print. The white border print we just tucked under an 1/8 of an inch or so. Hand sewed all 3 sides down. Looks great! Unfortunately, we found a few other smaller spots that came undone so just hand sewed those as well. Her Mama will have strict instructions not to wash the quilt. Thank you everyone for your suggestions!!
