I've had similar issue and you cannot repair, replace or leave out without hurting her feelings. She obviously wanted to participate or would not have volunteered. My opinion from experience is leave it as is. The other option is possibly saying you had 1 or 2 blocks too many and pieced them into the back so everyone's was used then add her's in back, make a second one for back if you need to. Or could her's be utilized as a label?
