Grandma would surely want it finished!!!
I know I would (mind you I am STILL not a grandma until Christmas this year :):) )

Sounds like Mom needs a little TLC. How long ago did Great Grandma die? What else is going on for Mom. Maybe she's dealing with feelings of loss.
I agree with you that the quilt deserves to be finished. Yet one more instance of "Timing is everything."

Is it yours or your mothers...yours finish it and treasure it..if it is mom's then abide by her wishes...

I think you should finish it. Sounds like an old wives tale, or maybe your mom is a LITTLE superstitious.

I posted earlier about finishing this quilt and after reading the thread I still feel finishing it is an honor but you posted later that your mother has it so time will be needed to convince her that the quilt means alot to you also. Have you showed her all the positive responses to your question?
Just what is her reluctants to having it finished if she is not superstisious?
I do hope you come to a resolution with your mom and get to complete the quilt. Finishing it would honor both GGM & DM.
peace

GVO9: I like the way you think!

Ditto.....definitely!

IF the quilt is yours as is...finish it with love. If the quilt belongs to your mother...leave it. It has the memories she wants already. She may change her mind and ask you to finish it in the future. jmho

Finish it. It will be a wonderful keepsake and memory of her.

I would finish it and cherish it as somethimg my grandmother started.

Lots of things in life are unfinished when a person dies. I would hardly say that is a good reason for letting it remain unfinished.

I agree, your grandmother would be so happy to see you finish it and enjoy it.

DO it.
