I want to start by saying that I have not read so far on the first 7 pages where anyone has been nasty or hateful in their replies. They read your post, digested it, and replied from their gut. If you did not want to hear their answers, you should not have asked.
This FDIL must be your first! Please don't alienate her. Once you do that it will be so hard to get her back into your grips! Love her for who she is and what she loves to do.
Not all of us like the same things. I have sewn and made my clothes since I was 10, but to quilt.......NO way, I never wanted to do such a thing until I was 59 yrs old. Now I love it.
As a Mother, Daughter, Granddaugher, and Mother in Law I know now I do not like people to force me to try to do something I don't want to do.
Give her space. She will eventually realize how beautiful your quilts are and if interested will ask you to help her get started making one.
Let her know you are there for her anytime she is interested you will be willing to help her. I would not start buying or making her kits though unless she asks you to. I don't know what kind of relationship you have with her, but that might be a little pushy for now.
DIL's and MIL's usually need to step softly until they really have established a good relationship. I know you will always want to be a good MIL and a friend to her. I have known to many people who have created issued that haunt their relationship for the rest of their lives. You have a long life and many good years ahead of you in your relationship with her and your son and their future family. Remember, they will be having children which will be your Grandchildren and you do not want to have s strained relationship during these wonderful years!
I know you want her as a quilting partner now, but give it time, if it is meant to be, she will come around. Don't rush or push it.
I am sorry you have taken all of the comments from people you don't agree with as nasty. I don't think any of them intended to be nasty. They, along with myself, read your post and gasped!! We understood that you were wanting to force her to become a quilter. We are not all meant to be quilters, maybe she isn't either. But even if she isn't, I bet she will shine somewhere else in something else that she does, and maybe she will be able to teach you something she enjoys.
I truely hope the two of you will have a long and strong loving relationship through the years to come.
Good Luck with however you choose to deal with this issue!
Sincerely not meaning to be nasty or hateful....
